You have to work against the zone..If you dont see if its very hard to beat it..Especially if your not playing team type ball on offense.. Ask Jim Boeheim the guy has lived and died by the zone in college..Which has better shooters for the most part and has a closer 3 point line...Jim says time and time again..Get my team into the tourney at any seed and we will succeed..Big east teams usually have more success against it cause they work against it alot...To go back to your first point Hoops..The other problem with a 2-3 zone is boxing out...So if the team your facing has a dominate big man he is going to get 2nd chance oppurtunities on rebounds...Which Miami did not have..Go back and watch Blake Griffin verse Syracuse a few years ago..He dominated..
The problem w/ that theory is SU and Boeheim usually disappoint every year in the Tourney.
