The Oakland Raiders plan to give Derek Carr some freedom to tweak offensive plays this season.

"I think it helps that he doesn't have to learn a new language again," second-year coordinator Bill Musgrave said. "Two years in the league, he had two different systems. Now, this year, he can feel like he has a good grasp of it and start putting his own spin on things and can put his own signature on the system. Things that he wants to see or tweak a quarter turn here or there, he can initiate that."

Carr, 25, had a 61.1 competition percentage, 3,987 yards, 32 touchdowns and 13 interceptions last season.
