It's the QB. Sacred cow around here, I know, but Josh Allen has been in the league long enough to know:
1) you can't be late over the middle
2) you shouldn't throw into triple coverage
3) that sometimes a sack and punting the ball away isn't a bad thing.
And yet he continues to make those mistakes. Tell me, at what point should the finger of responsibility be pointed at the QB who just crapped his pants on national TV? You can lead a horse to water, but if it does not drink, it's on the horse.
