Lots of shitty people and weirdos for sure. My high school had their first state champion in like ten years last season, and he got kicked off the team for stealing crap from teammates out of the locker room.
UNL's 2008 recruiting class had three multiple time Kansas State champs in it. Only one made it to campus. A Hutch wrestler was arrested for assault over that summer and a Gardner-Edgerton wrestler was arrested for the theft of multiple macbooks from a high school he had been training at.
That same summer UNO kicked off two all-american wrestlers from their team for posing for porn sites.
I can't verify this, but at regionals my junior year I was told that another wrestler there at slapped one of his teammates in the face with his penis in their hotel room the night before.
That's just a smattering of the terrible stories I have from over my high school and collegiate career.
