The offensive line is the one area where I think the Raiders are still weak.
Robert Gallery is a stud at left guard (if he can stay healthy), but outside of that no player stands out.
Mario Henderson has been inconsistent at left tackle, though will be given another year to prove himself at the position (which I thinks he deserves). I have never been a fan of Langston Walker at right tackle, as he suffers from a lack of mobility in pass protection, and Samson Satele has been a disappointment at center.
Cooper Carlisle is winding down his career, and doesn't show well against the bigger, stronger defensive tackles in the league.
This group leaves a lot of room for improvement, and there are players not starting right now who could be knocking on the door quite soon.
Khalif Barnes was a decent tackle in Jacksonville, and is another option at guard or tackle, and the Raiders drafted two very talented players this year in Jared Veldheer and Bruce Campbell.
Veldheer appears to be a little further along, getting second team reps at left tackle, and also being tried out at center. He certainly looked good at both positions against Dallas. Campbell has tremendous potential, and is backing up Cooper Carlisle.
I predict that regardless of injury, the starters om this unit will change.
