The senior has considered transferring before, even leaving the football team last spring while choosing a new destination. But this time it's for real, he says, and he'll be able to play at SDSU immediately because of NCAA provisions allowing seniors who have already graduated to pursue graduate programs at new schools when they are not offered at their current schools.
Butler graduated from USC in December and plans to pursue a post-graduate degree in the communication field, although the exact program has not yet been determined. The spring semester begins at SDSU a week from Wednesday, on Jan. 18.
Butler, 21, chose the Aztecs over Kansas.
He becomes the third USC Trojan to transfer this offseason. Last week, it was revealed running back Amir Carlisle would be moving to Notre Dame, near where his father is now employed at Purdue. And receiver Kyle Prater announced via Twitter earlier this week that he'd be transferring to a school closer to his home in suburban Chicago.
Butler, an Atlanta native, had considered mostly schools in the Southeast last spring but cast a wider net this time.
USC still needs roughly five more players to transfer before fall camp begins in order to stay under the NCAA-mandated limit of 75, assuming the Trojans sign their maximum 15 players on Signing Day in February.
