Winning the games you should win (Uconn, Wagner, SJSU, Fresno State, East Carolina).
Winning at home against just about anyone (Boise, Cincinnati).
Beating any rivals you play (USU... sort of).
Winning a big game (Any of the Missouri/Michigan/Nebraska/UCLA).
That equates to 9 wins minimum for a "successful" season in my book. Obviously would like to beat more than one of the P5 teams, but that to me is our success baseline.
