Wrestlers / jockstraps

[lololulu19]

Not that I want them to... but why is it that high school and college wrestlers do not wear jockstraps? I see so many videos where the wrestlers have very thin material over their cocks, which are often stiff.

Maybe they do that so the other wrestler refrains from grabbing them by the crotch and getting a handful of dick and balls? That would take a way a major point of leverage and control.
