I don't think Allen is uncoachable because Daboll was able to get him to play within the system.
The thing is, Allen's turnovers today for the most part weren't even forced. Just terrible decisions.
True, but imo winning early (Brady) takes so much pressure off later.
With Manning it was "yeah but..." And the pressure piles up and piles up each season.
Once you've got a ring you're always a winner
Belichick would tell "the QB" to get his ass off the field.
That's why Brady is a Buc now. But it worked.
Coaches need to make decisions and be the boss sometimes.
