Legion, who has played extremely well recently, had decided to look at other options after giving Amaker a verbal pledge about a year ago.
``I have always liked Michigan and Coach Amaker has always stuck out to me," Legion said. "He had a vision for me to be the leader of the program. A lot of other schools wanted me more as a role wing player."
Legion called Amaker with the news on Tuesday afternoon.
``I figured I should do it now so I can concentrate on being a better player," he added.
Another key factor for Legion, in addition to playing for Amaker, is playing with Manny Harris - who recently committed to the Wolverines.
``He's the other guard I need that will help me a lot," Legion said.
