FITTS DECOMMITS FROM USC
Kylie Fitts, one of the top defensive end recruits in the country, was just days away from enrolling at USC and planned to attend his first classes Monday. But Fitts surprisingly pulled his commitment.
“Something happened recently that questioned my trust in USC, so I'm reopening my recruitment,” Fitts told ESPN.com. “It literally broke my heart. I broke down and cried. It was so hard for me and my family. It's just what's best for me at this moment.”
Oklahoma was one of earlier teams to start recruiting the Redlands (Calif.) East Valley product, although he never took a visit to Norman.
The Sooners have commitments from three defensive ends already — Matt Dimon (6-2, 252), Ogbonnia Okoronkwo (6-3, 220) and D.J. Ward (6-3, 245).
