Tom, what is interesting is to see what you have talked about for years, - that is, teaching overhand throwing and hitting together, due to the similarity in sequences and synching of movements - is exactly what Candrea/Slaught/Enquist are talking about. Geez, how did you know that, Tom? I mean, with no real students and all... (sorry for the smoke screen reference...hard to resist.)
He DIDN'T know it. Just gravy-trained.
The material in question - RVP - is now more than 4 years old. When it was published, Tom was a happy MODERATOR at a SETPRO hitting site. Other than the occasional buffoonery of "arm action is king," there were NO SUCH comments authored by Tom in that time period.
He absolutely did NOT start talking about this until after he saw the RVP material. Period, didn't happen.
Slapper23, it sounds as if you work with hitters, so I'm inclined to at least listen to what you have to say. If you have worked with college level hitters, I'd be even more willing.
Guerry does not work with any hitters of any age, which makes his opinions just that.
THAT is content.
As for Lotieff, I know him, and have competed against him. I've never personally had the specific discussion, but I've overheard him discussing a number of hitting influences. His answer to a question about Englishbey was something like "Steve has a lot of the answers, though not all of the answers." It was NOT a disparaging comment. I have also heard him say that NO ONE instructor has ALL of the answers. And I dont think he panders to his audience, I think that is what he believes, so I would urge you to stop putting words in his mouth. Sounds as if you know him, and maybe he says something different to you. Or maybe you just INFER he says something different to you.
