First - some dumbass suggested Butch was too old.
Second - I don't recall Dino or Cristobol taking a broke-assed program with 31 scholarship reductions and building a team that played at UM in 2000, 2001, and 2002 - look it up if you're this unfamiliar with UM football.
Third - I don't recall them coaching under JJ at UM, then following JJ to the Cowboys, and then winning two Super Bowl rings as Defensive Coordinator - under two different coaches.
Now - who are the legends here in your postulation?
Sounds like all three.
