I disagree that Allen was “ rattled beyond recovery” as I got more of a sense that he was trying to make something happen rather than his nerves getting the best of him. Pettine kicked his ass, pure and simple, imo.
Your point about making a change is understandable, but there is also a benefit to having your young QB play adversity and getting reps, regardless. I’d like to share your optimism about Peterman, but I just can’t. Imo, it would have been far worse and we would truly have seen a QB get rattled beyond recovery as we’ve seen from him already. I think the only time we will see Peterman is if Allen gets hurt.
