I think the blocking scheme may have been intentional. Consider other bits of evidence:
-- Left tackle contributed to a double-team block, leaving the backside lineman, #55 (DE Gatkek Kueth?), free.
-- Quick snap, quick handoff, nicely opened hole between RG and RT.
It appears that the concept of the play design was for the RB to hit that hole before the unblocked defenders could get to him from the offside or the secondary. Unfortunately for the offence, Crouch recognized, reacted, and came through hella fast, blowing up what might otherwise have been a nice run.
So from that perspective, the RB needed to get his wheels moving quicker than he did for the play to work.
It's a team sport--rarely just one guy or one position group at fault, usually a combination of several pieces that just aren't quite clicking.
The really bad news is, if this IS the way the play was designed, it will likely never work in the SEC. Not only are there plenty of LBs with the speed of Crouch around the league, there are also defensive ends a heck of a lot faster than Mr. Kueth who could also have gotten to Banks before he left the backfield.
So I agree with all who said: bad blocking scheme. Either as drawn up, or as executed. Or both. But on top of that, let's get a little more urgency, Mr. Banks.
