GG helped our run game. Without him, it would either be a CC pass attempt or a DT run. GG also didn't have a big arm, but at least he kept the Defense "somewhat" honest.
CC runs like a 13 year old girl with big feet. (Picture it)
In conclusion, I think we would have won 3 games without GG. Iowa St. would have been a loss. Also probably CU and ku.
