LAS VEGAS — RJ Barrett has faced Zion Williamson countless times in practice as teammates at Duke.
Now they get the Las Vegas stage as opponents.
Barrett, the Knicks’ new 6-foot-7 lefty lottery pick, doesn’t have any grand advice for his Knicks teammates as the summer league team debuts Friday (9 p.m. ET) at UNLV against Zion and the Pelicans.
“He’s a great talent,’’ Barrett told The Post after the Knicks’ final summer league practice Thursday. “He’s going to do his thing. I’m going to do my thing. It’s about which team wins.’’
Barrett and Williamson were best buddies at Duke, which made the Elite 8 last spring before being upset by Michigan State.
