Why on earth would a Super Bowl winning coach (Gruden, Dungy, Cowher, Jimmy Johnson, Mike McCarthy, Tom Coughlin, etc) go back to the NCAA to coach? I know that Bill Walsh did it but he went back to Stanford. Has any Super Bowl winning coach, besides Walsh, gone from winning a Super Bowl to coaching college football? I would think its very uncommon and unrealistic to expect Gruden, Dungy or Cowher to ever consider coming here.
