Don't want to be a downer but I think writing is on wall this teams not long for western NY. Ralphs lack of visibility I take to mean his health is failing. And he hasn't budges an inch on not selling the team until he passes. There's no long term commitment to buffalo, and the woefully inadequate stadium can't get upgraded without it .even more problematic is the local yocals obstructing a viable Niagara falls relocation, which IMO is the only way to get a competitive bid to keep them in WNY.
What I see in the cards is a team that's losing out, won't make any management / coaching changes, and it quickly sold off to an LA bidder when Ralph passes, which could be any time now. With a reasonably good depth of talent , high draft slot and cap space to address needs at qb and LB, and no mega legacy coaching contracts, they will represent a compelling proposition for a new LA owner, attracting top tier GM/coaching talent.
So all this "whose going to be buffalos next head coach" is really a waste of time unless the unexpected happens and an unforeseen strong commitment to wny happens soon.
