I think it's more than the OL. It's the passing game. Even when the line blocks well, teams are still throwing more defenders at us than we have blockers. And if they're disciplined (like New England), they don't overrun plays and the stay with their gap responsibility. So it becomes that much tougher.
You have to exploit the defense with the pass to get them to back off. But to do that, you also need decent pass protection. So I guess what I'm saying is....it's the QB, WRs, and the OL.
To the point, I still want Ricky. No other RB on our roster could have stood up to the pounding he has taken. I look to the future in regards to Ricky.
