We moved guys around. A lot. Reading between some lines, I'm under the impression that Key was being told where to play certain guys and it wasn't the best 5 out there. I'm not sure how much I'm allowed to say on this board with naming individuals, but I'll just say to watch the film of guys who moved around. They were more effective in their new roles.
Edit: I'm also going to gripe again about how bad our TE's and RB's were in pass protection, partly scheme, partly missed assignments. Regardless, without looking up the numbers, a large number of the sacks we gave up this year were not on the OL
