I wouldn't say I am shooting from the hip here. You are correct in saying that there is no check with me system. There isn't. The offensive line sets the protections. True statement. By going silent count, the quarterback (by design) is not checking into right plays based on late walk ups simply because he is waiting for the snap to come intently while the offensive line is still actively setting protections. While that process is going on, the qb mental picture can change and the offense has been victimized multiple times this year by these blitz varieties. That I could gladly show you on film.
The natural blitz beater built into this offense is usually the boundary side slant flat progression. On 2x2 it is the halfback check or flat. Those are both ture. When Miami kept more into block this game vs pitt, it came with a cost. The mirrored 2x2 had none of the customary blitz beaters attached with it.. It essentially put the qb on an island. It relied on the offensive line protecting right and having the quarterback read the field beyond that.
I have never once caught miami audibling this year from 2x2 and running a split call. I had Mark Richt actually calling the same mirrored switch combo 5 out of 6 times on third and long going over the course of two games. That was run vs varied coverages and never once sight adjusted. The mirrored routes run the mirrored routes that is as rigid as it gets.
I don't want to say "trust me" beyond that. But I had a way to double check my math on this one. If I looked at my paper right that is. But some concepts in this offense have adjusted capabilities, in this case. No.
Still, the over reliance of mirrored concepts is extremely evident in this offense, and it was my opinion that it limits this offense at times. That's all. Great counter argument though.
