To anyone that will tell you that 'launch angle is hooey' -- show them this:
There's simply not better visual representation than can be made of what the
good launch angle guys are trying to explain.
And this was from Ted Williams book "The Science of Hitting" published in 1970.
This isn't new. It's not witchcraft. It's the right way to do it. Nothing Pujols says in that entire MLB segment actually runs opposite to anything the launch angle guys say. All he's talking about his his first movement. The rest of it...well, you can see by the photo of his swing. He does EXACTLY what Williams and modern acolytes of his will tell you to do.
