Unless he's still injured, I think one of the biggest mistakes Red has made this year is refusing to play zone, when he did it in the 2nd half of last season to good effect. He has a 7-4 guy who at least doesn't turn away from guys driving the lane. He has five fouls to give, even if you only play him 5 minutes.
I will never forget Patrick Ewing's freshman year in the national championship game against North Carolina. Ewing got called for about 4 goal tending calls in the first 5 minutes of the game. It didn't matter. It set the tone for the rest of the game.
Jeremy McNeil, Conrad McRae, Etan Thomas. Those guys changed games, even when they fouled out in 10-15 minutes of playing time. I'm stupefied that we play such terrible defense, and he almost never tries anything different.
Where's the press? One game for about 10 minutes. Zone? Maybe a couple games for a total of 20 minutes, being generous.
You have to mix up defenses. You have to change things up. That is Rule 1 of coaching - if they are beating you at what you're doing, then change it up, FFS !!!!
