IMO - this was as bad of a performance as we've seen from Zach. But if you look back at each of his bad plays, he apparently is slipping, when he tries to plant his feet. If this were an NFL game, they'd simply changed out his shoes or the length of the cleats. In college, I guess you have to wear what you brought with you. The body of his All-American work, suggests this was a aberration, due to the weather conditions. Boomer!
