I'm not necessarily better or more experienced....but at first glance, I definitely agree that your team underperformed this season. Rochester reminds me a bit of my Macalester team this season. I have final four expectations as well, but seeing this performance makes me nervous. ;)
I looked through the game against Austin, and one big thing stood out to me. Hallum shot way too much. I know you ran into a double team, but he was also matched up against a very good defensive player (79 DEF, 59 ATH) that naturally would have shut him down anyway. Hallum is a good scorer, but you should have either moved him to SG to take advantage of a weak defender (45 DEF, 37 ATH) or decreased his distro big time. His scoring efficiency killed you in that game, especially since you were running slow down. Can't waste shots when playing fewer possessions...
What 3pt setting did you have Coury on? Looks like he might have been set to 0, but I would have moved him to -1 or -2 to take advantage of the mismatch at SG. My gameplan would have included trying to drive to the hoop as much as possible with Coury and pile up the fouls against Tall.
Those are just a few quick thoughts. If I have some more time later, I'll try to look at your other games.
