Hey, you can be right but I am thinking exactly the opposite. I think the raiders are set at running back with Justin Fargas, Dominic Rhodes and Michael Bush.
Tommy Kelley plays 3-tech but also play defensive end I think he will play in rotation at both positions. They will use i Gerard Warren and Terdell Sands at the nose, and Kelley and maybe someone else at the other tackle positon. I can see the raiders taking either a defensive tackle or end here.
It is the raiders, you never know with them.
