College football: Up-tempo offenses create rift in Pac-12

College football • Crosstown rivals Lane Kiffin and Jim Mora stand on different sides in debate about up-tempo offenses in college football.

Kiffin, the Southern California coach, is concerned about the possible safety ramifications of a style of play that crams an extra 20 plays in a 60-minute game.

He says with all the emphasis being put on player safety these it makes sense to at least examine whether up-tempo offenses increase the risk of player injuries.

UCLA's Mora, meanwhile, has embraced "fast-break" football in his first season as a college head coach.

And he says that after being around the game for 30 years, "I don't think there is a safety issue."

• South Carolina's athletic compliance department is looking into contact between defensive end Jadeveon Clowney and rap mogul turned sports agency head, Jay Z.

Spokesman Steve Fink said Wednesday the department was aware of reports about conversations between Jay Z and Clowney, the 6-foot-6, 274-pound lineman who's considered the top pick in next year's NFL draft.

Athletes are permitted under NCAA rules to talk with agents, just not reach agreements about future representation. Athletes cannot accept benefits from agents or their representatives while in college.
