I guess from a fans perspective, I'm mad he didn't go for it because I'm assuming the bills have 0 chance against the Pats. So tie against the Colts and lose against the Pats, the season is done.
I understand the coach can't mark losses on the calendar, but he should also know it's almost an impossible task to win those last 3 games, especially given the tough schedule ahead. That's where I think he mis calculated the decision to play"not to lose".
9 and 7 gives you a descent shot so you can maybe afford to lose one more game. 8-7-1 gives you no shot
