I really like this debate. I obviously like the fact that people share the same opinion as me. But it is fascinating to me that what is being said by those who agree with me is counter to what 98% of the pitching coaches and pitchers are doing. Every college team I come across in my coaching has their pitchers do this wrist flip stuff. Now I do believe in strengthening the wrist and hand just like I think conditioning other parts of the body is important. But that flipping drill does nothing and is based on an ill conceived notion of the pitching mechanics.
