I think McDermott is the problem.
That's probably why there's bad blood with him and Daboll. McDermott wanted a wimpy boring offense and Daboll just did whatever he wanted.
And it worked and everyone loved it, which probably hurt McDermott's pride. Then his beloved defense blew the 13 seconds game.
Obviously everyone on the team was aware of the tension and I'll bet many sided with Daboll. His side of the ball was rolling.
Now Dorsey is just some guy that Josh hoped would be Daboll but McDermott can control him so it's bland vanilla offense
