Because human nature says many times it is in "bad taste" to talk about other humans body parts, we laugh off the notion that people are catogorized in this manner. However, if you ever been to a livestock auction all you hear is muscle/bone structure, length, development vs age, disposition, gait/movement, and other characteristics that humans may think of as insulting.
In the end, professional and college sports use those parameters and visual assessments to form initial potential. It is a "meat market" where prime cuts are identified early. How do you think the tall/long pitcher syndrome started?
I remember when my son was in HS being looked at as either a pitcher or position player and one scout saying "He's a pitcher only, LOOK at his a$$", and all the other scouts nodded their heads in unison and jotted a note. I went home and told my son to hang up the bat away because all the scouts were focusing on was his butt. Later on I filled him in on the pitching portion of the comment
