I'm sure someone more knowledgeable will correct me, but our scheme isn't that complex.
Three primary things occurred as I saw them.
First, Georgia defense didn't even consider Quinn a threat to run and their secondary was anticipating him to check down under pressure.
So they pinned their ears back up front, pressed QE and he stressed, didn't make quick reads, hesitated to run, and went to his check down. They didn't consider him a threat other than underneath and bet that under pressure he'd make mistakes. They were right, and the OU games was a good template to base the plan on.
Because the Georgia D front 7 didn't have to honor contain on QE running outside they spied him a bit, played the under routes well and D line bested our Oline. Consistently.
Sark had a script written, it is a plan that requires reads on the secondary to throw to the open space. Well, QE was under pressure, not running and quickly trying to force check down throws. That allowed the not great to this point Georgia secondary to stay cover zone. Quinn wasn't a long ball threat and wasn't a run threat.
Then, seeing all this, Sark didn't modify his script until he brought Arch in. What happened.. a touch down.
OU showed a d plan to frustrate Quinn, allow D line to go hard in the paint and defend him.
So.. yes, Georgia did know what we were going to do, and how to stop us. They also knew Sark hates going off his script. It's Sarks biggest weakness. It's a problem.
So in order of priority:
1) Quinn is not longer ANY threat to run, at all. He also defaults to check down.
2) This allows good Dlines to beat play pressure every down and worry less about contain post D read. Our Oline isn't good enough to stop this type of consistent pressure.
3) Sark won't alter his script when the one he drew up is floundering terribly. He waited until we were down 3 scores to do so late in the 2nd. That's too late against good teams.
4) Sub issue related to 3. Sark didn't go to hurry up down 2 scores with 9 minutes in the 4th. His plan.. didn't change to adapt to the reality.
I admit there's a lot more i don't know than I do, but thats what I saw. I'd actually love someone with more knowledge to educate me on where I'm wrong. Seriously, learn me if I'm off.
