Ohio Guys....one of the local Cincinnati association secretaries ran it up the flag pole....Here's the Ohio answer:

During pre game warm ups both team A and Team B are shooting at their respective baskets. Team A leaves the floor and returns to the locker room. Team B after all of Team A leaves the floor starts the three man weave full court as part of their warm up. Once Team A returns to the floor Team B stops their full court exercise and goes back to the half court. The question is this legal or illegal.

Per John Dickerson - Asst. Commissioner and State Rules Interp - The Answer is Legal

I had never seen this happen...until tonight. I agreed with Mr. Dickerson.
