I think he deserves his due in both the ROF and the HOF. Yeah, he alienated Elway and had some issues, but you don't coach 10+ somewhere if you are not doing something right in the NFL, AKA "Not-For-Long".
I will say this about Reeves, he somehow managed to get get a lot out of what I would consider a not overly talented roster year in and year out. Sure the Bronocs had their players, but other than a few like Elway, Dennis Smith, Atwater, Mecklenburg, and a few here and there, it was not much. We did not have great linemen, WR or RB when he coached, but we won. I think that says something. If Levy got in, he should too.
