Young is the most intruiging prospect in the system, he's supposedly up to 7'0, which is probably taller than any pitcher in the history of baseball.
But he seems to be coordinated despite his growth spurt, and as he fills out and learns how to use his huge frame, could get a big uptick in velocity - plus obviously he's going to have a release point a foot closer to the plate. The fact that he already has a passable curve and changeup bodes well for his future.
But it's not just velocity with big guys, even if it flatlines at say 91-93 or so, having that much power allows some pitchers to throw "effortlessly" over 100+ pitches, so they sustain velocity through a game.
Always worry when a high effort guy throws hard, the guys that seem to last are the ones that don't seem to break a sweat.
