At the end of the day the Bills had not one, but TWO chances to win this game on their own terms.
That basically means your game plan failed.
If anything, I'm coming around to the idea that the Bills need to move on from Daboll. Offense is a bit too finesse. Everything should be tailored to maximizing Allen's abilities, and that's going to allowing him to play off of play action, giving him more 1v1s, and that happens with a running game and 2-3 established receiving threats.
Offense should be base 11, 12, and 22, and should be a lot more even between run and pass with personnel geared towards that.
