Jim Otto Jersey , this time for a lateral move. Running backs coach Jemal Singleton has taken the same position with the Cincinnati Bengals, the team announced today.Singleton spent last season as the Running backs coach under Jon Gruden. He joins former QB coach Brian Callahan who takes the offensive coordinator job in Cincinnati.Also recently leaving for a promotion elsewhere was DB coach Derrick Ansley who was hired on as co-Defensive Coordinator at the University of Tennessee.There are now three key position coach position yet to be filled by the Raiders. QB coach may or may not be a position the Raiders see as a high priority to replace as Greg Olson and Jon Gruden are both have QB coach origins. But filling the RB coach and DB coach jobs are absolutely important.New Defensive line coach Brentson Buckner is the only known position coach hire by the Raiders this offseason. He was already on staff when they coached players at the Senior Bowl. AJ Neibel has reportedly been hired as Head Strength and Conditioning coach, replacing Tom Shaw who was fired late last season.Neither the Buckner nor Neibel hires have been officially announced, which could mean the other hires have also been made but not announced yet. Often times the team will wait and announce the hires together. There’s already far more turnover than anyone really expected after just one season on staff. Follow @LeviDamien With Khalil Mack and Amari Cooper gone from the Raiders, the next question maybe isn’t whether the team wants to move quarterback Derek Carr but whether it can keep him.Marcus Thompson II of TheAthletic.com reports that Carr currently has a “fractured relationship” with his teammates. The reportedly fractured relationship between Carr and his teammates is rooted in a loss of confidence in the quarterback, as exacerbated by game film from the London contest against the Seahawks that “showed what looked like him crying after being sacked and injuring his arm.”“They saw his face,” Thompson writes. “They heard his whimper. They witnessed him explain on the sidelines. They assuredly watched it again in film session. It鈥檚 hard to see how Carr can lead this team again.”It was indeed curious, to say the least Kenny Stabler Jersey , to see video of what appeared to be Carr crying in the melting-face way that a kid would cry after falling off his bike. If Thompson’s report is accurate, Carr’s teammates regard it as something worse than curious.This doesn’t mean the Raiders will move on from Carr, but whether and to what extent the locker room believes in Carr could be a factor in coach Jon Gruden’s ultimate assessment as to whether Carr should or shouldn’t be the quarterback in 2019. As noted on Monday, his contract pays out an average of $19.6 million over the next four years, which could make him tradeable. If not, the Raiders will have to decide by the third day of the 2019 waiver period whether to keep Carr and pay him a guaranteed salary of $19.9 million next year or cut him and find another quarterback.
