I mean, you are absolutely right. Most short guys don't make it because they literally cannot throw hard enough to make it because of their stupid f***ing little arms and tiny boy bodies. Like, they aren't even getting scouted in high school because they are throwing 79 or they are not getting scouting out of college because they are throwing 88 with no physical projection at all. Marcus is an exception because he does throw hard. After it becomes obvious that he is an exception, people should stop comparing him to the class of short people - it has no real bearing on his outcome. Short guys will also tend to have stupid little tiny girl hands, which can't spin the baseball the same way and have trouble throwing effective changeups.
Anyway, my Pardinho post really had nothing to do with his height, just his age and distance from the majors and already having elbow soreness and stuff.
