Kalin Hall's is, Tim Mctyer wanted his here, Ty Detmer's nephew will probably be, there's others that I'm forgetting, but the point is that some Lavell alumni obviously disagree. Chad Lewis is deeply involved, as are other alumni to a certain extent.
Buck's kid on the other hand wasn't offered, and not only was he not good enough, then you bring in an entitled alum who wants a voice so it's probably better he's wasn't brought in imo.
with that said, BYU/Bronco can do much better with alumni. The problem is I don't see Bronco changing a ton, it's just not his personality, which is why I include BYU because some guys there can make changes.
