Cronin averaged 12 points, 12 boards and 8 rejections while lacing them up at the high school which produced Andray Blatche.
In picking Michigan, Cronin became the first recruit in 2008 to pledge allegiance to John Beilein. He's ranked the No. 36 center in the nation by Scout.com.
"It feels great to tell you the truth," Cronin said. "He's rebuilding the program and I'm excited to be one of the first players to join team.
"(Beilein's) stuck with me since I was young. When I first got to Henninger he watched me. He saw potential in me and stuck with me. He's renowned and everyone knows how good of a coach he is".
Cronin, a true post who says he's been shooting it well enough this spring to mesh well with the system Michigan runs, indicated it was tough to tell hometown Syracuse "no."
"I'm sure I'm going to hear it. I love the Syracuse program and it was a tough decision but I definitely feel like I picked the right school."
