Steelers RB Le'Veon Bell vs Ravens LB C.J. Mosley: Bell is the key to victory for both teams. If the Ravens can contain him and make quarterback Michael Vick beat them, they have a good chance of winning. Bell missed the first two games because of an NFL-imposed suspension, but had 62 yards on 19 carries last week. Mosley, with 20 tackes, is second on the team behind fellow inside linebacker Daryl Smith (21). He'll have a tough job handling Bell on those cut-back runs. More importantly, Mosley has to cover Bell out of the backfield on passing plays, something he has struggled with. Edge: Steelers.
