I'll repost this, since it got lost on the last page:
Resident Bills fan here. I came on to correct some of the Brian Daboll narrative I'm seeing.
Daboll coached in the nfl for many, many years prior to coming on with the bills. You can look it up - all of his offenses prior to Buffalo were in the bottom of the league. When the Bills hired him, fans were pissed because he never had any kind of success anywhere. At Alabama, he started Jalen Hurts (over Tua, more on that later) who couldn't seem to complete a pass that year. They were a running offense, even at QB, and could not throw the ball. Nick Saban finally overrules Daboll at half time of the national championship game and puts Tua in for Hurts. Tua lights it up and they come back and win. Questions loomed as to how Daboll could have seen and coached both qb's in practice all year long and decided not to play Tua. They placed the blame on Hurts, and said he wasn't good enough, because he couldnt throw the ball. Then Hurts transfers out of Bama and finishes 2nd in the heisman, throwing the ball all over the lot, something he couldnt dream of doing under Daboll. It seems Daboll was the one holding that offense back the whole time, not Hurts. An odd year for Daboll at Bama, to say the least.
Daboll then comes to Buffalo. We know the progress Allen made, but Bills fans, and people in the know, understand that Jordan Palmer and Josh Allen are responsible for the progress, and not anyone else (McDermott, Dorsey, Daboll). The difference in Allen's mechanics was night and day, which is something Palmer corrected, not Daboll. Add in the fact that Daboll never had success with a QB in his 20+ years prior, and we can see Daboll probably didnt have some magic turnaround all of a sudden.
Daboll has been criticized all year long by Bills fans (and McDermott) for his play calls and offensive philosophy. He refused to run the ball, at all costs, even when defenses dropped 9 back. It cost us games. McDermott had to step in and correct that personally, but its still been an issue until recently.
If Daboll takes a job, I dont think Bills fans will be sad to see him go. One of my pet peeves in NFL circles is when teams hire the coordinator of the offense who has an MVP type QB, as if they are responsible for the offense's success instead of the QB. Adam gase comes to mind. The chiefs OC is another one. Daboll gave 100% of his effort to Buffalo, so we wish him well wherever he goes, but I think if there's a team out there hiring him because they think he's some sort of "offensive guru," they are sadly mistaken.
