Wolph,
This is going to be my last post to you in this thread so if you want to be the internet tough guy and get the last word in you go and do that. Your aren't arguing, you are what we call "poisoning the well." Even in the last line of your post, you try to pollute the content of my post by attacking me.
The version of the 2-3 zone that I linked to is Syracuse University Coach Jim Boehiem's 2-3 zone. Any coach who is worth anything uses this version of the 2-3. Its the most popular variation of the 2-3 zone. Your right that the NBA doesn't run it but what does that have to do with anything. Every NCAA DI Tournament team that ran a 2-3 last year ran it and every team that used a 2-3 in EuroBasket this year ran this variation. The USA NT uses it sometimes on sideline out of bounds plays and used it to shutdown Spain on the last play of a very close exhibition game before the last Olympics.
My knowledge doesn't come from an arm chair. ;)
