Chargers make a lot of sense for Daboll, if he wants to be a HC.
Bengals could also be intriguing, if they fire Taylor, who IMO had no business being hired as a head coach and was a product of "people who have spent 5 minutes with Sean McVay" a couple years back.
I would love Daboll to stay, if he chooses, but if he gets a chance to move up the ladder you can't blame him.
The good news is that the Bills would be able to have their pick of OC candidates, given Allen and the offensive weapons here.
