Dissecting the last play of regulation...ISU let Love drive to (IMO) the perfect spot on the floor to make the long desperation heave. If the opponent needs to make a desperation 3ptr with that little time left, the defense needs to herd the dribbler to the sideline. If the ref calls the foul, then the opponent has to pull off the make/miss/rebound/putback scenario. You just can't let the opponent dribble unencumbered to the ideal spot in that scenario. You can call the timeout after to first missed FT to set up the defense, or practice that scenario so the guys know what to do.
Some on-going issues I saw in the AZ game that aren't conducive to a deep tournament run (both already mentioned):
1) Got to make FTs, particularly on the road
2) Got to be able to break big scoring runs
