I find these kind of post somewhat amusing. "He hit 93 at 14" or "he hit the ball 450' at 16". You know what that means? He matured really early, nothing more. He's not going to be throwing 126 mph at 25. Look at Harper, I think I saw he hit a ball like 500+ at 15 of something like that. What's he hitting the ball now? His longest this year has been 441.
So the kid is going to make the show no doubt. Might be a HOF'er, but right now there are like 70+ pitchers hitting 100+. So it seems to me when he gets there he's going to be "another face in the crowd".
There are limits to what the human body can do. It can only throw a baseball so hard. It can only hit a baseball so far. There's a ceiling, some people just get there faster than others.
