And a lot of guys played shortstop in high school too. A lot of guys don't actually start pitching until they are 14-16 because all of a sudden they start growing into bodies that the other kids aren't growing into.
Either way, it doesn't matter. The point is, that Chapman starting to pitch at 16 isn't rare and it really isn't something that should even be brought up as some sort of "detrimental" thing.
