That was definitely a max effort pitch from a kid with a big arm. Sorry to hear about the problems. Make-up is real important and sooner or later you get exposed. It can only be hidden for so long. I hope he conquers those problems. DINOson used to snap his arm back across his body like this kid does but a couple thousand reps concentrating on follow through I think broke that some. I was always told it wasn't healthy for your arm.
Oh yeah and btw once a drinking problem, always a drinking problem so think about that when you start experimenting. Everything in moderation.
