Jolietboy-
Again, what is the point of this? What value does it provide to a HS pitcher? At that point it isn't some random drawing, it's already been selected that the player can pitch.
If a 5'8" pitcher who throws 88 mph is on your HS team, what are you going to tell him?
And, importantly, your "physics" are not correct. Two very prominent engineers/physicists involved in pitching (Trevor Bauer and Paul Nyman) have both said that tall and short pitchers have different advantages. Taller pitchers generally have the advantage of leverage (longer levers/arms/legs), while shorter pitchers have an efficiency/movement pattern advantage (easier to move and accelerate more efficiently and coordinate actions). Either can be successful. Now it is "easier" perhaps to teach a tall person (with long levers) to throw harder, because they have greater margin of error, which is why most MLB folks for years thought "you can't teach velocity," however, as many have shown (Kyle Boddy, Wolforth, Wheeler, Nyman), you can teach throwing mechanics and efficient movements. With the proper strength and conditioning, and instruction, there is no reason a smaller pitcher cannot throw hard.
Go even further to extremes, would you expect a 7'1" person to throw hard? Or would it be tougher for him to have the proper coordination, hip shoulder separation, and acceleration/movements to throw hard? As you get larger levers, synching them up can be pretty tough. If longer levers are of the utmost in importance, why wouldn't taller people make better sprinters? [Throwing a baseball is more akin to a sprint, or a sport with a short burst.]
I think jolie's point is that if those advantages were any where CLOSE to being equal advantages, we'd see a lot more guys pitching in the big leagues in the 5' 8" to 5' 11" range. We don't. Which means that whatever advantage being 6' 5" has, significantly outweighs any advantage being 5' 8" may have. Significantly.
