Fran knows if they just straight up play basketball ISU will destroy them. They have to muddle up the game, make it ugly, maybe stop play with a few pushes and shoves, and try to get in the heads of ISU's players to get them off their game.
If that works, which it is right now, they will win.
This team is not reacting well to the environment and intensity of this game. This is exactly what I was afraid of. I know some of you want to poopoo their environment, but this is the one game their crowd and players bring all they've got.
