You admit you're wrong re the timing in the frames you showed being early rather than late, I guess. Cool.
Go research O'Leary's predictions. He said Searage hurt Locke's timing, Hamels is too elbowy and is risky when his velo is up, etc.
I don't mean to jump on you really--but I also don't want people to seek out O'Leary as if he's some magic answer without knowing the full story. That's the reason I'm reacting to your using him as the arbiter of "safer" mechanics. Nothing personal.
O'Leary hedges constantly. He abandoned Price after Price got hurt and then claimed the Red Sox changed his mechanics. What do you think the odds are that the Red Sox changed the mechanics of a guy they just paid $$$? 0%. He plays both sides of the fence so that when someone gets hurt he can say "I told you so." That's why most of his surviving models are retired baseball players now--by definition he can't be wrong because they're not pitching any more.
At one point he said, Carlos Martinez, Justin Verlander, Yovani Gallardo, David Price, and Jeff Locke were great models. Then he abandons them when they don't do well (but is now back on the Verlander train after last year). and blames the team for "changing them." It's a theory not worth following because he creates a moving target and can't admit he's wrong.
