If Roberts did end up there it's only because he didn't get in to Miami originally....
Willie Roberts from Southridge back in the early 2000's is another one.
On top of Roberts not getting into Miami, some dude listed Stockar McDougle and Torrance Marshall. Both of those guys were JUCO guys, so they didn't go to OU straight from HS in South Florida.
In fact, I'm pretty sure McDougle went to JUCO in Texas, which is close to OU. Marshall wanted to go to UM but couldn't get in. So he wound up at Kemper Academy then found his way to OU.
