If Bohl sticks with Vigen, then I'm in support of evaluation of the staff next year. If he moves on from Vigen, then I'm in support of another 3 years at least.
I really think a build at WYO will take longer than 4 or 5 years. With that said, I agree that it isn't just the record this season but more of how we've looked at times. I get that and fully agree that lack of depth is concerning. Honestly, though, for anyone it is probably a bit of a learning curve to recruit and compete at WYO. I think UNM is in a similar boat and they probably should have kept Rocky.
I don't think the offense needs to change drastically, but I do think it needs tweaked to create more mismatches, have more misdirection to freeze LBs, and maybe reduce the reads for young QBs. I'm speculating on the last one. I would also say that including JA, they need a better QB development coach.
Anyway, my take is if Bohl adjusts, give it time. If not, well, see what next year brings.
