Pretty solid post. I agree and disagree with it.
Game one: was a totally team loss. Allen looked pretty bad and there were contributing factors which you laid out. What surprised me was his " yips" and poor decisions.
Game two: I disagree with him being "shell shocked." He's been in the league long enough not get to this point. The Dolphins D isn't all that. They are ok perhaps a tad above average. He didn't face relentless pressure. Imho, you could see He was off, lacking confidence, anticipating the rush, jittery in the pocket, and throwing inaccurately. He was better in the second half but still not great. His first drive was very good. At some point, I felt like the dolphins were deflated and the Bills took advantage of that.
Disagree with the " hero ball" mentality. I think this is where Allen has grown by leaps and bounds. He frequently throws the ball away and lives for another play. I didn't see any " hero ball" plays vs Miami.
