Anderson leaves Oklahoma State - although he has one more season of eligibility remaining - as the fourth-highest scorer in Cowboy history with 1,811 career points. He scored 735 points during the 2009-10 season, which is the second most in a single season in school history behind Bryant Reeves' 797 points.
Anderson joins former OSU athletes Okung, Bryant and Riley as first-round draft choices in recent months.
Okung, the All-American offensive tackle for the Cowboys, was the sixth overall selection by the Seattle Seahawks in April's NFL Draft, and Bryant was the 24th pick by the Dallas Cowboys.
Then, Riley became the first Oklahoma State women's basketball player ever to be selected in the WNBA Draft when the Cowgirl point guard was selected eighth overall by the Los Angeles Sparks.
Anderson becomes the first Cowboy taken in the first round of the NBA Draft since Joey Graham was the 16th overall selection of the Toronto Raptors in 2005.
