Penn State - Obvious reasons. Damn program should have been shut down. Instead they sued the victims and got off basically scot-free in the end.
Virginia Tech (they may be #1, I still remember the hype machine ESPN had for them in the early 2000s) Beemer ball? Play defense and emphasize special teams. How earth shattering. Yawn.
Michigan - fans are obnoxious, and they ruined the heisman trophy forever.
OSU - the fans. Second only to uga fans for pure obnoxiousness.
