I am not opposed to anything, outside trading Josh Allen.
The OC point is a valid one, any young guy will get poached after a year or two (and most can return after they get fired). Bills could hire a veteran OC who’s a failed HC, likely wouldn’t gather much HC interest again.
In my opinion, this summer is a bad one to need a new HC. I’d rather see them keep McD one more season and get themselves a true, established OC to come in and take over.
If they fail next year, fire everyone. Ben Johnson will likely be in year 2 as an OC, DaBoll will probably be available, and who knows who else.
