Walker joins shooting guard Michael Frazier II in leaving school early for the draft.
The 6-foot-10 Walker averaged 4.7 points and 3.5 rebounds as a sophomore this season, proving to be one of the biggest disappointments in Donovan's 19 years at Florida. A McDonald's All-America in high school, Walker came to Gainesville with loads of hype. He fell way short of expectations, playing in 49 games and starting six in two years. He averaged 11 minutes, 3.7 points and 2.7 rebounds.
Walker says he's ''excited to continue pursuing my dream of playing professionally.''
Donovan says Walker is ''a great kid with a lot of potential, and everyone here wishes the absolute best for him.''
