Its possible that Daboll and McD didn’t always see eye to eye. Whether they did or not is probably mostly irrelevant imo, especially now that Brian is gone. What matters more is whether McD and Josh Allen will see eye to eye going forward. If, and I say if, the 13 second episode is at all indicative of the HC’s mindset, inclinations and character (more than just a mistake that anyone can have the misfortune to commit) then I could foresee problems given Allen’s aggressive competitiveness. They aren’t paying McD a quarter billion dollars.
