as far as videos go, hillhouses is very informative, and tells you why he believes certain mechanics, and maybe more importantly talks about drills and mechanics that are counterproductive, i have loaned it out to one of my assistant coaches so i couldnt tell you how long they are, his mechanics are similiar to most experienced male pitchers you talk to , no hellow elbow, teaches the riseball, peel drop, movement pitches produced from different pressures on fingers, natural relaxed release. One reason I bought his videos was so i could give it to some of my hellow elbow coaches in my community so they could see how an elite pitcher throws these days. I thought maybe they would listen to him since they wont listen to me !!!!!!!
