The Suns Get Whistled More Than A High School Gym Class

This NBA season has produced more than its fair share of ridiculous, eye-popping statistics. Russell Westbrook got his record-tying 41st triple-double of the season on Tuesday. The Rockets shattered the league record for threes made in a single campaign with two weeks left to play. And 20-year-old Devin Booker, who’d never even scored 40 points in a contest before, somehow logged 70 points in one game last month.But Booker’s team is on the cusp of crossing a less-than-ideal threshold as things wind down: The Phoenix Suns, who lead the NBA in fouls by a wide margin with 1,963 so far, are on pace to eclipse the 2,000-foul mark, which would make them the first NBA club to hit that mark in 10 years.The Suns commit 25 fouls per game (the NBA average is 20) and send their opponents to the free-throw line an NBA-high 29 times a night. It isn’t necessarily a new problem, since Phoenix allowed opponents to go to the stripe more than anyone last season, too. But the team’s fouls are up 10 percent from last year, and the team is becoming a bit of an outlier by fouling more often, given that NBA foul rates have decreased over the past decade as more and more shooters space the floor, leading to less contact from play to play.The chronic fouling is a symptom of two much larger issues: 1. The team’s inability to contain their opponents on defense, where the Suns allow 109 points per 100 plays, third-worst in the league. Being that bad leaves their players out of position, often leading to more desperate fouls as they try to recover. And 2. Phoenix’s relative youth and inexperience, especially in the post, where it’s fairly common for players to struggle with foul trouble at the beginning of their careers.This talented group is still developing, both physically and mentally. The Suns are one of the NBA’s shortest and lightest teams, which might make them a bit easier to push around. But Phoenix — which last month used the youngest starting five in NBA history — also has plenty to learn when it comes to countering the offensive tricks and techniques that veteran players acquire over the years.“You ever seen a young group of guys play against a group of older guys in pickup? The older guys somehow manage to physically take advantage of the younger guys without making it look like that’s what they’re doing. Then the young guy starts to hit back, and it’s completely obvious? That’s what we look like sometimes,” coach Earl Watson told me last week during his club’s East Coast trip. “Players in this league are so good, and our guys are still learning how to be aggressive without committing obvious fouls.”Those gaps in experience are most apparent in scenarios where a single defender is being asked to hold his own: 1-on-1s and post-ups. The Suns have committed the second- and fourth-highest rates of shooting fouls this season when guarding 1-on-1s and post-ups, respectively,1Phoenix has been whistled for shooting fouls 14 percent of the time in isolation scenarios and about 15 percent of the time when guarding post-up opportunities. according to Synergy Sports.It’s hard to fault the players’ intent, despite the dismal results. They often sacrifice their bodies in hopes of forcing a turnover, but many times they haven’t established good enough positioning to ward off defensive-foul calls. This has been especially true of some young players, like Booker, rookie power forward Marquese Chriss and fourth-year center Alex Len, who are 1-of-18, 5-of-28 and 0-of-14 when it comes drawing charge calls this season. (Those numbers are pretty abysmal, considering that the leaguewide average charge rate is 40 percent.)Phoenix’s learning curve has gotten considerably steeper in recent weeks, since the Suns elected to shut down a handful of healthy veteran players, including usual starters Eric Bledsoe and Tyson Chandler, in pursuit of some lottery ping-pong balls and a chance to give their younger, less-used talent some spin over the final month of a losing season.That has meant fielding lineups that have little institutional knowledge of how to defend without fouling.“If I’m the only young guy out there with four veterans, those four can kind of direct traffic and help cover for me when I mess up,” said Chriss, who commits 5.5 fouls per 36 minutes, tied for the NBA’s fourth-highest rate among players who’ve logged at least 1,000 minutes.2He’s tied with Len. “But when it’s a situation where everybody on the floor is, at most, 3 or 4 years into their career, that’s kind of tough, because then we’re all kind of lost, and still learning how to communicate with each other as players.”It’s not just an issue of youth. There are several other, less-examined factors that help explain why they’ve committed so many fouls. Phoenix plays at a blistering pace, handling more possessions than most, which puts the team in a position to commit more fouls than any other club. The Suns have been in more close games where they trailed late than any other team, meaning a decent number of their infractions were likely intentional and committed in hopes of stopping the clock. And it’s worth noting that Phoenix also comfortably leads the NBA in offensive fouls. So, not every foul Phoenix commits is a symptom of the Suns’ weak defense.Make no mistake, though: The Suns do an absolute ton of hacking, and they usually get called for it.“Refs officiate games with a certain rhythm. They’re used to a certain speed and rhythm. When you jump out of that rhythm, it’s easy for them to see, and you’re going to get called for it,” said Chandler, an NBA champion who joined the league as a teenager and went from committing more than 5 fouls per 36 minutes in his fifth season to eventually winning Defensive Player of the Year. Chandler added that the Suns, much like he was as a youngster, are often overeager to make a play, and wind up swiping or jumping when they shouldn’t.Nevertheless, struggles and all, Watson is an eternal optimist. He takes ample time most days to walk through film of the team’s fouling tendencies, and he told me that he feels his team is only a reinforcement or two away from a huge turnaround if the young players keep developing.“I was with OKC during Russ’s first year” — Westbrook, of course — “and I always let [my Phoenix players] know: That year, [the Thunder] won 23 games. The next year they won 50, and did it because their young guys had gotten so much experience and developed a supreme confidence.”Phoenix may not go on to write the kind of success story that the Thunder did, at least not next season. But if putting in a year at the School of Hard Knocks helps this team improve on defense, maybe the Suns will eventually be able to say that this furious foul pace was a worthwhile learning experience.Check out our NBA predictions. read more

Did OSU torpedo 2011 season

The Boys of Columbus face two key early-season tests that could derail their road back to New Orleans for next year’s BCS National Championship Game. OSU struggled in every road game except Minnesota in 2010. After two cupcake home games against Akron and Toledo, the Buckeyes play at Miami (Fla.) in week three. The Hurricanes played zombie football the last half of 2010 — anyone who watched Notre Dame dismantle them in the Sun Bowl could see that. The new eye of the Hurricanes, Al Golden, is a strict disciplinarian. He’ll have slackers running stadium stairs or shown the door. Come week five, the Spartans will visit Columbus. If the NCAA reduces the suspensions of Pryor, Herron, Posey, Adams and Thomas to four games, this could be their first game of the season. But if the NCAA upholds the suspensions, it’s likely Joe Bauserman, Jordan Hall, Corey Brown, Chris Fields, Andrew Norwell and Adam Bellamy will play major roles in beating Sparty, who loses veteran players on defense but returns with a strong offense. If OSU goes without the suspended five against Sparty, it might be a home underdog, which is rare for the Buckeyes. The last time this happened was against USC in 2009. The Sugar Bowl triumph feels good, but OSU might have mortgaged away another national title run in the process. “Through all adversity lies a blessing.” Solomon Thomas said that after Ohio State’s Sugar Bowl victory over Arkansas on Jan. 4. In a game full of turbulence, it was fitting that five of the Shameful Six played fabulous roles in the win. But now it’s time to look to next season. By letting those players work their magic in the bowl, OSU might have cursed its 2011 national title hopes. Thomas, Terrelle Pryor, Dan Herron, DeVier Posey and Mike Adams say they’ll return next season, putting OSU ahead of the Big Ten class: Michigan State will lose key players, including All-American linebacker Greg Jones; Wisconsin will lose powerhouse Scott Tolzein, winner of the Johnny Unitas Golden Arm Award, given to the top senior quarterback; Iowa has to start over; and Michigan is nowhere to be found. Big Ten newcomers, the Nebraska Cornhuskers, will compete for the 2011 conference crown with quarterback Taylor Martinez. However, it’s a catch-22 for OSU: The Shameful Six were allowed to play in the Sugar Bowl, but all except Jordan Whiting can’t play the first five games of next season for their part in Tattoo-gate. OSU appealed to reduce the suspensions. The Sugar Bowl win salvaged 2010 for the Buckeyes, who snapped their nine-bowl-game losing streak against the SEC, dating to 1978. By letting the suspended athletes play in the bowl, OSU might have pulled the plug on a 2011 National Championship run. read more

Mens soccer looks to bounce back against Oakland

Redshirt-junior goalkeeper Alex Ivanov (32) takes a goal kick during a game against Northwestern Oct. 20 at Jesse Owens Memorial Stadium. The teams tied, 0-0.Credit: Eric Seger / Sports editorThe Ohio State men’s soccer team is getting a break from its Big Ten schedule Wednesday, when it welcomes the Oakland Golden Grizzlies to Columbus.Oakland (5-3-5, 3-0-1) is a member of the Horizon League, but Buckeye coach John Bluem said his team would be wrong to take the small conference school lightly.“We’ve played Oakland many times before and they are a very good attacking team,” he said. “One of the things we’ll have to make sure we do is to first, (is) bounce back after (Sunday’s game). It’s a short turnaround to play again on Wednesday night. We’ll also have to make sure we respect our opponent, we can’t look at Oakland and say, ‘This is a team from a smaller conference and we should be able to win.’ Well you know, that’s not how it’s going to happen for us, we’re going to have to fight every single game as hard as we can if we want to get a result.”Oakland enters the match against the Buckeyes (2-6-5, 0-2-2) coming off a 3-0 loss to another Big Ten team, then-No. 14 Michigan State. The Grizzlies sit in second place in the conference.Defense has been crucial to The Golden Grizzlies’ success this season, as they have only allowed an average of 1.23 goals per game this year. Oakland junior forward Joey Tinnion leads the team with 14 points (six goals and two assists) in 2013.Bluem said the Buckeyes have been “riding the coattails of an incredible goalkeeper this year,” and the defense will have to remain strong in Wednesday’s match.OSU redshirt-junior goalkeeper Alex Ivanov said his job is to keep the team in the game at all times and that the team needs to remain focused in its upcoming matches.“It’s very important to keep the spirits of the younger guys up and make sure that they’re still checked in and focused on the season,” he said. “(The season) is still not over — everything is up for grabs. I think because we’ve been so close, the soccer gods will come through. We’ll get something eventually.”Three of OSU’s last four opponents have been ranked in the top 20 at the time it played them. Sophomore midfielder Zach Mason said confidence from playing those teams, after tying all three of them, will help the team finish the season strong.“We’re going to do what we’ve been doing (in practice),” he said. “I think we have a lot of confidence. You know, we’ll stick to the basics, stick to what we’ve been doing, we’ve been really close and I think we are right there.”Wednesday night’s game is set for 7 p.m. at Jesse Owens Memorial Stadium. The team’s next match is scheduled against Cleveland State Oct. 27, before it resumes conference play against No. 13 Penn State in Columbus Nov. 2.An earlier edition of this story noted that OSU had lost to the last three ranked teams it had played. The Buckeyes have in fact tied all three of these opponents. read more

ReRegistration Period For Honduran TPS Beneficiaries Starts

first_imgPhoto courtesy of Center of Central American Resources, CRECENSupporters of the TPS for Honduras and other Latin American countries rallied in Houston on May 1, 2018.U.S. Citizenship and Immigration Services (USCIS) announced Monday that Honduran nationals who are current beneficiaries of Temporary Protected Status (TPS) and want to maintain their status through the effective termination date of January 5th 2020, must re-register between June 5th 2018 and August 6th 2018.According to a news release distributed by USCIS, re-registration procedures –including how to renew employment authorization documents— have been published in the Federal Register and on uscis.gov/tps.All applicants must submit Form I-821, Application for Temporary Protected Status.Additionally, applicants may also request an Employment Authorization Document (EAD) by submitting a completed Form I-765, Application for Employment Authorization, at the time of filing Form I-821, or separately at a later date.Both forms can be downloaded for free from the section on TPS at the USCIS website.Employment authorizationThe news release added that USCIS will issue new EADs with a January 5th 2020 expiration date.However, because of the timeframes involved with processing TPS re-registration applications, USCIS acknowledges that not all re-registrants will receive new EADs before their current EADs expire.Therefore, USCIS has automatically extended the expiration date on EADs issued under the TPS designation of Honduras for 180 days, through January 1st 2019. This extension includes individuals who have EADs with an expiration date of January 5th 2018 and who applied for a new EAD during the last re-registration period but have not yet received their new EADs.Situation in HoustonAccording to data compiled by the Immigration Legal Resource Center, as of April 2017, there were approximately 6,000 TPS beneficiaries from Honduras living in Houston, The Woodlands and Sugar Land.USCIS said in its news release that Hondurans with TPS “may wish to consult with qualified immigration attorneys or practitioners about their eligibility for another immigration status or benefit, or whether there is any other action they may want to take regarding their individual immigration circumstances.”However, as Houston Public Media reported in May, the upcoming termination of TPS has some in the local Honduran community considering to stay in the United States as undocumented immigrants.

Robots shed more light on evolution w Video

first_img Robots Reveal Insights into Evolution Explore further Researchers Laurent Keller, from the University of Lausanne, and Dario Floreano of the École Polytechnique Fédérale de Lausanne studied Alice and Khepera robots controlled by input information from the robots’ sensors and neural networks. They loaded short basic instruction codes into the robots’ operating systems, with random variations that changed every generation, in “virtual mutations”. To simulate natural selection, only the code for the most successful robots was selected and passed to the next generation of robots.In one experiment they programmed robots with six sensors on one side and two on the other to navigate a maze. They then selected the robots most skilled at avoiding collisions. After fewer than 100 generations the robots could navigate through a complex maze without collisions, and had learned to keep the side with six sensors facing in the direction of travel. A) The predator robot (right) facing the prey robot (left). B) Six examples of pursuit and evasion strategies that evolved over the 100 generations of selection in one of the replicates (see main text for description). The position of the prey at the end of the trial is indicated by the empty disk and that of the predator by the black disk (the lines in the disks correspond to the frontal directions). Image credit: doi:10.1371/journal.pbio.1000292.g004 Play Evolution of collision-free navigation. In the initial generations, robots can hardly avoid walls (one robot even approaches objects). After 50 generations, robots can navigate around the looping maze without hitting the walls. In another experiment they programmed groups of robots to push tokens along a wall to a marked area to win points. They selected the robots that gained the most points to pass their code on to the next generation. Over time altruistic behaviors were observed, in which robots sacrificed points if the entire group would benefit, and the robots cooperated to push larger tokens together to earn more points. As in nature, the robots followed the biological principle of kin selection, in which they only helped robots having the same code lineage. Play Evolved “Khepera” robot performing exploration and homing for battery recharge. The robot enters the recharging area approximately 2 seconds before full battery discharge. In other experiments some robots with good eyesight were programmed to pursue other robots, which were faster. At first the predators found the prey and headed towards it, while the prey were programmed to move away. After 125 generations, the predators had developed the strategy of lying in wait and attacking the prey robots’ blind spots, while the successful “prey” robots learned where the predators waited and ensured their sensors were always facing the predators. Play Coevolved predator and prey robots engaged in a tournament. After locating and moving towards the prey, the predator cannot reach it because the prey can perceive it with the rear distance sensors and moves faster. The code used in the experiments was extremely short, which proves that complex behaviors can emerge from a simple set of instructions. The paper is published in the Public Library of Science — Biology journal. (PhysOrg.com) — Swiss scientists have proposed that if robots could evolve through natural selection the result would be robots that would help each other, cooperate, and be capable of hunting. Their experiments follow on from earlier studies reported by PhysOrg, which used robots to shed light on evolutionary processes.
