With C Satele having an injured knee, but still probable, should the Raiders sign some extra insurance at the offensive line? The Jason Campbell incident reminded the Raiders that at any given time anyone can go out. This is true for the o-line. If Satele were to get injured, Wiz would slide over and Bruce Campbell would most likely come in at LG. this leaves us with no C or LG back-ups (except maybe Barkesdale/Heyer moving in to the guard spot). Nonetheless, should the Raiders make a move for free agent C/G Shaun O'Hara? O'hara has been a pro bowl presence the past three years. And could help mentor the young line. Not to mention he'd most likely come cheaper than usual as he hasn't been able to get a job and it is now week 7.
