Here's my assessment on Purdy after seeing him two games in a row now. He can't stretch the field vertically. Two of the worst deep balls I've seen at D1 in a long time today. He throws it as hard as he can, with poor trajectory and no spiral. Purdy needs to play dink and dunk and use his mind to beat you, but he missed two huge runs on the read option by keeping the ball instead of giving it up. One to Breece and One to Jirehl. Sure the balls that were intercepted were deflected but even those weren't good throws. His timing was off, he has a hard time finding throwing lanes over our huge lineman, and Hall and Kolar aren't 100%.
Dekkers takes away much of the problems with our offense. He can stretch the field, he was on time with his route progressions, he was accurate, he can throw over the line, he can run. I think the decision is easy. Brock is a good QB, but not against good defenses.
