Or . . . and bear with me here, because it is a radical idea that nobody has talked about at all (except for a whole bunch of us), Kraft actually, legitimately, has not made a final decision yet.
It has been two days. I can see how Kraft fully expected BB to coach at least one more year but now is reconsidering due to the craptastic football we all had to witness this year, the draft position they have, and the recent track record of BB picking offensive talent. But he also has a 20+ year relationship with the GOAT coach who brought him 6 Lombardis and who he sided with in a show down with a QB who he talked about like he was his son, so firing him might not be that easy of a decision to get to. He might just need a couple of days to figure out what he wants to do here.
All of that said, he better make a decision sooner rather than later either way.
