NORMAN — Austin Reaves loathes the nickname, but that didn’t stop Christian James from chanting it incessantly as the two players walked off OU’s practice floor Thursday. “Showtime, Showtime, Showtime,” James kept on, before slightly exaggerating that Reaves scored 60 points in the late afternoon practice. There was no chance Reaves, a transfer guard, was going to shush James, OU’s senior scoring leader. All Reaves could do was smile and endure the rite of passage as a first-year Sooner. The practice gym is the only place to watch Reaves play in an Oklahoma uniform. He’s one of the most overqualified scout team players in the country. Reaves has to sit out this season after transferring from Wichita State — the team his new squad faces at 11 a.m. Saturday at Chesapeake Energy Arena in Oklahoma City. “Yeah, it’s gonna be awkward,” Reaves admitted. The Newark, Arkansas, native transferred in May after playing in 66 games spanning two seasons for the Shockers. His transfer didn’t result from a lack of success or playing time. Reaves was a regular for Wichita State, averaging eight points in 21.5 minutes per game as a sophomore. Reaves shot 43 percent from 3-point range last season and set a school record by making seven consecutive threes against Tulsa last January.
