Well then don’t hire guys who aren’t sold on Fields. That shouldn’t be an issue. Build around your QB.
There’s also no available potential HCs who are clearly a better HC candidate than Daboll. There are no guarantees. Other than Harbaugh, who I don’t think is coming, the closest one is is Flores. And based on his track record with OCs and some of the stuff that has come out of Miami I’m not so sure I trust him with my quarterback. At least with Dabboll you’re getting a good play caller on offense.
