Marcus Smart: Two seasons is it

Oklahoma State's Marcus Smart, previewing NBA-level play this week as the only collegian to participate in a USA Basketball minicamp, says he won't pass on the pros again as he did earlier this year when he decided to return to the Cowboys.

"It's safe to say that if, by the grace of God, I'm healthy and everything, this will be my last year at Oklahoma State," Smart said Tuesday in Las Vegas after practice, according to Yahoo! Sports. "Nothing will change my mind on that."

Smart, 19, was seen by many as a lock to be selected in the top five of this year's NBA draft after a freshman season in which the 6-foot-4 guard averaged 15.4 points, 5.8 rebounds and 4.2 assists a game.

His performance punctuated the season for a Cowboys team that finished 24-9 and 13-5 in the Big 12 but was ousted in the round of 64 of the NCAA tournament by the 12th-seeded Oregon Ducks. Oklahoma State had been seeded fifth.

"[Oklahoma State] understands," Smart said of his plans. "They didn't figure I was coming back this year. They were just as surprised as everyone else."

Oklahoma State coach Travis Ford said last week that the Team USA camp, put on by national coach Mike Krzyzewski, would be valuable for Smart, who is coming off playing a reserve role for the gold-medal-winning FIBA U-19 U.S. team in Prague.

"It's a great opportunity for him to compete against the best," Ford said. "He will learn a lot on the court but also away from the court. I'm excited he will be able to talk and get to know many of these great pros, pick their brains on what it's like to be in the NBA and what it takes to become a great pro."
