James Jones

Raiders WR Michael Crabtree admitted he has a chip on his shoulder after a frustrating free-agency experience left him with a one-year, prove-it deal that guarantees him only $1.3 million. (He can make another $400,000 for 70 catches or 900 yards, $1.4 million for 100 catches for 1,400 yards and $400,000 for being named to the Pro Bowl.)

“I have a lot to prove,” Crabtree said. “A lot to prove. Ain’t got nothing to lose and have a lot to prove.”

“I would say the year prior to last year was me recovering, trying to get back right,” Crabtree said. “This year I don’t feel a thing. Just go out there and play.”

After a disappointing free agency experience, Crabtree will be motivated, but his role in Oakland is unclear. The team already has James Jones, Rod Streater and Andre Holmes, and it's not clear just how many snaps Crabtree will earn as he joins that group.
