"Will has committed and will sign tomorrow with Indiana," Weston (Fla.) Sagemont coach Adam Ross told Scout.com.
According to Ross, Sheehey, a 6-foot-5 senior small forward, had a great official visit to Bloomington (Ind.) and felt like he could help the Hoosiers.
"He loved it," Ross said of the visit. "Indiana is a special place academically and if you are a basketball fan I don't know if there is a more historic place. It's a big time place if you love the game."
"Will really believed in Coach Crean and believes that he's going to turn Indiana basketball around and put them back on top of college basketball where they belong," Ross said.
"Coach Crean believes in Will and believes that Will is one of the guys that can help do that," he added. "They have a fantastic business school and Will is a great student and the business school was something that will was definitely interested."
Sheehey is Indiana's second commitment of the 2010 class. He joins three-star prospect Victor Oladipo.
