Ben McLemore is one and done at Kansas. Ricky Ledo is none and done with Providence.McLemore, Kansas’ talented freshman guard, was among several underclassmen who wasted little time in declaring for the NBA Draft on Tuesday, the day after the college season ended.Ledo, a Providence, R.I., native, practiced with the Friars this season but never played because he failed to qualify academically. Practice was enough, apparently, to make him a possible first-round pick.Indiana All-American Victor Oladipo announced he was giving up his senior season to enter the draft. New Mexico’s Tony Snell also announced he was going pro.The father of Louisville guard Russ Smith, who helped the Cardinals win a national title by beating Michigan on Monday night, said his son will also enter the draft.In Lawrence, Kan., Jayhawks coach Bill Self said he’s known for a while it was time for the 6-foot-6 McElmore to go.“Ben kept telling us in February, ‘Don’t worry about getting anybody else. I’m coming back,’” Self recalled. “I said, ‘Yeah, right. You want to make a public announcement?’ … If he told me he wanted to come back, I would have told him, ‘We need to look at this again.’ ”That’s because McLemore’s stock couldn’t be much higher.The second-team All-American is expected to be a lottery pick in June after breaking the Jayhawks’ freshman scoring record held by Danny Manning. McLemore averaged nearly 16 points for a team that went 31-6 and won a share of its ninth straight Big 12 championship.Lewis thrilledNinety-one-year-old Guy Lewis has difficulty speaking because of recent strokes.But the huge grin on the face of the former Houston coach on Tuesday conveyed his elation at finally being inducted into the Naismith Memorial Basketball Hall of Fame a day before.Lewis coached the Cougars for 30 years, but is best known for leading the Phi Slama Jama teams in the 1980s.His daughter Sherry Lewis said, “It’s pure joy and we’re not even upset that it took so long … Dad is used to winning in overtime.”Briefly • Texas A&M: University spokesman Jason Cook will become senior associate athletics director for external affairs.
