Fwiw, I wouldn't advocate changing the defense at all, my criticism is we just don't seem to be executing what we are doing that well. There are little things that can be done. For example, I saw one series where LaSalle missed a shot, got their own rebound, took another shot from deep, the ball bounced pretty hard off the rim, and we had either 3 or 4 guys all just standing around looking at it. LaSalle player pounced and grabbed it, kicked it out and they hit a 3. That's just maddening small detail stuff where your guys are all looking around at each other I guess hoping someone else is going to secure the ball. The rebounding mentality there has to be wired so differently that you are almost instinctually going after the loose ball, full bore, no hesitation.
So it's those kinds of small things that the coaches do need to notice and adjust for. I suppose their mentality is that it may not matter, but the results indicate otherwise.
