The Buffalo Bills signed running back Reggie Bush on Monday, adding experience to their uncertain offensive backfield.Bush, 31, is expected to compete with veteran Mike Gillislee and rookie Jonathan Williams for a backup role behind LeSean McCoy in training camp.Its good to be back to football, Bush said Monday. I felt like the opportunity here was special for me and the team, for the coaching staff and for the fans as well.Karlos Williams, who showed promise as a rookie as the Bills No. 2 running back last season, is suspended for the first four games of the regular season for a violation of the NFLs substance abuse policy. Jonathan Williams was arrested for suspicion of DWI earlier this month, although if the 2016 fifth-round pick is suspended, it likely will not happen until later in the upcoming season or until the 2017 season.Offensive coordinator Greg Roman has already discussed with Bush the possibility of using both him and McCoy on the field at the same time this season.Bush also becomes a candidate to return punts for the Bills. None of the three players who returned punts for the Bills last season -- Marcus Thigpen, Denarius Moore or Leodis McKelvin -- remains on Buffalos roster.The move is interesting in that in 2012, Bush and then-Jets coach Rex Ryan famously did some verbal sparring before the Jets and Dolphins first meeting that season.?Leading to the game, Ryan said Bush would get a little hot sauce. Bush injured his knee before halftime and later said he thought the Jets were looking to hurt him.Earlier Thursday, Ryan was asked about his hot sauce comment.See, thats whats so funny. That was a respect thing. I had to put a little extra hot sauce on him. You know whats funny, literally it was more of our attention, he said. I think he misunderstood me and ran for like 100 yards against me the next time we played, so that wasnt good.Bush isnt holding the comment against Ryan four years later.Me and Rex have had some battles, going back a long time, Bush said Monday. So we have history, obviously, from New Orleans to Miami. But Ive always been a fan of Rex, and now getting a chance to play for him I think is going to be pretty cool.As a member of the San Francisco 49ers last season, Bush tore the meniscus in his left knee slipping and falling on an exposed concrete surface surrounding the field in the Edward Jones Dome in St. Louis. He was later placed on injured reserve, ending his season.In January, Bush sued the St. Louis Convention and Visitors Commission, which runs the Edward Jones Dome, over his injury.The former 2005 Heisman Trophy winner and the second-overall pick of the 2006 draft has struggled to stay healthy the past two seasons. He was released by the Detroit Lions after an injury-plagued 2014 season in which he was limited to 297 rushing yards in nine games.Bush has totaled 5,493 rushing yards and 3,508 receiving yards in 10 NFL seasons. He eclipsed 1,000 rushing yards in 2011 with the Miami Dolphins and again in 2013 with the Lions.Now entering his 11th season, Bush is re-evaluating his future after each season.I think Im just taking it year-by-year, Bush said Monday. Im just happy to be back to football. After this season is over, and granted that Im able to stay healthy and be myself, Ill make a decision after that and see. Barry Bonds Pirates Jersey .

In the hours after Sunday nights presidential debate, professional athletes rushed to Twitter to denounce Republican nominee Donald Trumps crude illustration of a locker room. Wrote former Vikings punter Chris Kluwe, I was in an NFL locker room for eight years, the very definition of the macho, alpha male environment youre so feebly trying to evoke to protect yourself, and not once did anyone approach your breathtaking depths of arrogant imbecility.Locker rooms have been the focus of much attention in the days since The Washington Post released a 2005 recording of Trump bragging about his behavior with women, including grabbing them by their genitals without their consent. In a statement posted several hours after the tape was released, Trump called his words locker room banter, and he echoed that sentiment Sunday night.I dont think you understood what was -- this was locker room talk, Trump said. Im not proud of it. I apologize to my family. I apologize to the American people. Certainly Im not proud of it. But this is locker room talk.It shouldnt be a surprise that Trump rushed to the safety of the locker room to excuse his words. For years players, coaches and media have excused?crude language, hate speech, immorality and even criminal acts in actual locker rooms as toughening-up exercises, harmless hazing or even team bonding.Even as the world around it evolves, the sports sphere is still very much a haven for antiquated ideas, misogynistic beliefs and over-the-top masculinity. By making the locker room a sort of mythologized space where men are free to shed the morality and humanity of the outside world, were, in essence, excusing that behavior.When the Miami Dolphins locker room was splintered by the Richie Incognito and Jonathan Martin bullying scandal, former players came out in droves to mansplain how Incognitos actions were just a part of locker room culture. Incognito called his words and actions an indication of the teams closeness and brotherhood.In case youve forgotten, Incognito regularly hurled slurs and threats at Martin, texted with a teammate about rifle scopes that are perfect for shooting black people and directed racial slurs at the Dolphins assistant trainer, who was born in Japan.ddddddddddddThe Dolphins fired offensive line coach Jim Turner and head athletics trainer Kevin ONeill in the fallout after a workplace harassment report was released, but multiple sources reported that Dolphins general manager Jeff Ireland told Martins agent that Martin couldve stopped the bullying and avoided disrupting the team had he simply punched Incognito. And that sentiment wasnt just expressed internally, plenty of players-turned-media agreed that Martin shouldve retaliated with his fists.Not surprisingly, the solve it with violence strategy doesnt always produce the best results. A couple of years after the Dolphins incident, Jets quarterback Geno Smith missed two months of football and, ultimately, lost the starting job after getting punched in the face by then-teammate IK Enemkpali. A five-million dollar guy playing the most important position on the field was on the bench because of locker room culture.The locker room, no matter how different it may be from a boardroom, a factory or a cubicle, is still a workplace. Of course, each workplace will have different standards for whats deemed socially acceptable; a bar will have different standards than a kindergarten classroom. But a workplace should always feel safe -- physically, mentally and emotionally -- for all employees. Trump felt secure seeking solace in the notion of a locker room because for years weve made excuses for actions that should be inexcusable in any venue, under the cover of a culture that should have been left behind years ago.Its the same sort of thinking that goes on when schools send girls home to change clothes because their legs, arms, shoulders, collarbones or chest are distracting to boys. Arguing that boys will be boys and they cant be expected to control themselves is as insulting as assuming that grown men are incapable of acting appropriately in a locker room.So while I understand athletes wanting to put distance between themselves and Trumps comments, they -- and we -- should be just as invested in making locker rooms a place people no longer go to hide.
