oh gosh, I'll wait till you confirm this: You just said baseball is not a power sport?
It's not a strength sport, but the whole game of baseball is a bunch of power movements...
All incredibly powerful movements.
As For Mr. Mills, keep in mind he is a pitching coach AND a marketer.
He stuff is logical to a degree. If you review what he says in depth though, you will realize what he says is far from the complete truth or whole explanation of something.
Keep in mind what Mills calls weight training is essentially body building because he says it doesn't increase power, it is slow, and doesn't help explosiveness. All of which can be done via proper weightlifting.
Also, RIstar, basically what Mills is saying is that once you are fit your so called funcational training won't do anything either.
This all goes back to his theory that the only way to throw harder is to pitch from a mound. Which is definately debatable, somewhat correct, but to definite a statement to be completely correct.
