Carr better than expected: The Raiders original plan for Derek Carr was to not have the rookie play in 2014 unless something “castastrophic” happened. Funny how things change. The former Fresno State star has impressed the coaches during workouts and could challenge veteran Matt Schaub for Oakland’s starting job. The next step in the process for Carr will be working against a live rush — one of the things that concerned scouts about the second-round pick — but he has certainly opened some eyes in the Bay Area. If the rookie indeed opens the season as the starter, he’ll still have limited fantasy appeal. But add this to the list of camp battles to watch.

Lynch to retire?: Marshawn Lynch has made it know that he is in the market for a new contract. As such, he reportedly plans to skip the team’s mandatory minicamp. That has led to more talk of Christine Michael gaining a larger slice of the offense. Could Lynch’s next move be retirement? Sources close to the running back say that he has considered walking away from the NFL. For the time being, let’s file this away under “June talk”. The upside is that it could give Michael and Robert Turbin more opportunities in practice, which isn’t a bad thing. But for now, we’re fully expecting Lynch to be in camp later this summer. If things change, look for a shakeup at the top of the draft ranks.

Stewart says he’s healthy: The Panthers have tried to host a running back rotation for each of the past few years. It’s been tough because Jonathan Stewart has struggled to stay healthy. But the veteran rusher says that’s behind him and he’s looking forward to 2014. Stewart has played a combined 15 games over the past two seasons and hasn’t come close to approaching the 1,100-yard season he posted in 2009. It’s not likely that he’ll have that kind of production this season — even if he stays healthy for a full 16 games. A healthy Stewart damages the value of DeAngelo Williams.
