They have a strong football history starting in the 80s. They have a well defined and unique brand, and a big and passionate fanbase. They're also on the east coast. I agree they get overhyped, but it's not completely unfounded. Perception in college football lags by a few decades.WVU is one of those teams who had a good run starting 20+ years ago (averaged 9.5 wins/year from 2002-2011) and is still getting hype and praise based on that.
The pre-season hype was that Greene is an NFL QB, definitely didn't look like it last night.
