Reinhardt had announced earlier this week that he would be leaving the Rebels after a freshman season in 2012-13 in which he averaged 10.1 points, 2.5 assists and 2.0 rebounds per game.
Reinhardt's decision to leave UNLV caught many in the college basketball world by surprise considering the extensive playing time he received in his first collegiate season.
UNLV coach Dave Rice said Reinhardt was leaving because he wanted to play point guard, but sources close to Reinhardt said there was also a desire to create plays rather than focus on being a spot-up shooter. Regardless of the reason, the Trojans are getting a player with the kind of skills who could eventually have an impact in new USC coach Andy Enfield's up-tempo attack.
Reinhardt originally gave a verbal commitment to USC while he was at Santa Ana (Calif.) Mater Dei but later de-committed before deciding on UNLV. Reinhardt will sit out the 2013-14 season under NCAA transfer rules and will have three years of eligibility remaining.
