I somewhat disagree with all of your takes about that playoff game.
Yes, the Colts D-Line was giving us problems, but the Bills were able to adjust and in the 4th quarter Allen hit Diggs on that deep touchdown pass.
That touchdown should have(not should of) put an end to the game, but the Bills defense went to sleep and the Colts roared right back and got a touchdown very fast.
Then the Bills won the game on a fumble caused by Jordan Poyer, but the official in New York City, in their infinite wisdom, overturned the correct call, because they wanted a dramatic ending.
While the Colts gave the Bills fits in that game, overall the Bills did what they had to do in order to win that game.
If they should happen to face each other in the playoffs again, I think the Bills will be up to the task in beating them again.
