IMO the reason Doug left probably has a little to do with all the reasons everyone speculates. He didn’t get along with the front office, 4 million dollars, he thought he could get the Jets job, etc....
Whats funny to me though is there’s a good chance the Jets HC job will become open soon. If Marrone is still interested in it he did himself no favors by going for 2 points against the Jets late in the game!
