My daughter has been going to Bill for about 5 months... it's unreal. By his own admission he isn't doing anything new and revolutionary, just cutting out the "junk" that has worked it's way into the way people teach pitching (many of whom cannot and have not actually pitched themselves). All I can say is when you watch him and see how and why he does certain things, you'll scratch your head at the others. Maybe I'm just a proud dad but, I can see a complete difference in my DD now.
The same thing that is his biggest asset as a coach is also the toughest thing about going to him for lessons: he is in such demand for his games. He literally is flown over to Europe for a weekend game series and goes ALL OVER the USA. But, from what I'm told his winters are 100% committed to coaching which we plan to take advantage of. Last I knew his season ended over Labor Day but, he said something last time I saw him (3 weeks ago) that he signed on to pitch for the King and His Court in Hawaii and Puerto Rico.
Also, I agree with Frost coach about the video. The info on there was/is impressive and the filmmakers did a hell of a job.
