Another theory, nice. If zone worked, more coach's would run it, I promise.
I'm not sure why I am responding to such nonsense, but I'll simply say, no.
Haha yea "go guard someone" is man to man defense. C'mon, let's get serious. We can't have serious discussions when people are going to post things like this. In what league that you played in was man to man defense "go guard someone?" Intramurals? YMCA league? You need to watch Butler play. Yea, they just go "guard someone."
They only ran some zone at times, not for long stretches and it was out of necessity. (foul trouble, change of pace) A match-up zone is basically a sagging, switching man to man defense with man principles, which if you were keeping up I already stated. Get off match-up zone, we are talking man vs. zone, no match-up zone. Once again if you were paying attention match-up zone has already been covered, and I already said it is a good enough defense if run correctly, as it is basically switching man to man. It's still not as good as good man to man defense.
