Ozzie is uncut BTW. That was said in his porn video by one of the ladies. If I am not mistaken, he is now displaying his wares in underwear whereas in past seasons he was never seen in underwear.
"Coach" gets a lot of TV exposure, and often, it is in his grey underwear.
There are some other hot guys, but they don't (yet) get much TV exposure.
Note that the show tends to show underwear a lot in the first couple of episodes and then the actors all get similar board shorts for the remainder or the season.
