Yeah, this wasnt a surprise. But it stopped their momentum cold and by the look on the head coach's face, well he may rethink his strategy. But who knows, he will probably get some questions about it, which tends to make a coach stubborn.
I understand wanting to give your future QB some play, but you should have some flexibility in your plans. Anytime Ive seen coaches rotate QBs regardless of situations, it has been a failure.
