I'm gonna stick up for Mr. Glass here on one point, the "2-3 man to man". My favorite college basketball team, the michigan state Spartans used to run a "Matchup 2-3 zone" under their old coach Jud Heathcote. This defense was a zone base but defenders shifted and at times it even looked lik a 3-2 zone depending on the offensive set. The idea was to not get stuck in a bad matchup on the zone. So if a good perimeter player drove to the baseline, the forward and guard would switch spots in the "zone" (it usually looked like man defense on the ball). They also used a fair amount of trapping out of this set.
