I know this may sound sacrilegious. But Geno may be learning from Dawn. Over the past few seasons, Dawn played lots of different lineups, usually winning games, but often not pretty. Even in the loss yesterday to UCLA, Dawn played 12 players, 9 of whom played double-digit minutes.
The benefit is that everyone is well rested for the Big Games in March, and the added depth you gain from giving lots of players meaningful PT becomes a serious advantage to deal with the various opponents and matchups you face in the tournament.
