I've gone back and forth on this.
Like, after last year, Belichick really did have to go - it was clear the train had hit the end of the track, and there was nothing really left there - too many issues between him and ownership.
Now, the thing is, you should have done an actual rebuild, instead of 'Fire Bill and we'll be fine', which is what they did. And a QB fell into your lap, and you've wasted a year of him.
I don't think this team goes anywhere with Belichick as the coach this year - but I feel like with the weaker schedule, they could have at least been more competitive. But is that worth keeping him? I dunno.
