The kid has something going for him that can't be taught, hand speed. He could tone it down and his rev rate will still be 400. You have to remember he's a kid. Nobody at 17 even worries about 18. To me he looks like a cross between Fagan and Amleto. Do you think either of those guys were as smooth at 17 as they are now? As he gets a little older, wiser,stronger and an even better bowler than he already is, he will refine his game to compete at higher levels.
Right now he bowls JBT. His only cares in the world are striking, hoping they put the girls in skirts on the high end of the house, and where we going to eat when we get done.
