Hilliard Davidson High School senior Keith Heitzman, who helped lead the Wildcats football team to a Division I state championship his junior season, has changed his verbal commitment from Vanderbilt to Michigan.

"Ever since (Michigan's) coaching change, I opened up my options," said Heitzman, who made the decision Jan. 22. "Illinois came into the picture. I was building a great relationship with them, but then Michigan threw an offer out there and I knew I couldn't pass that opportunity up, so that's where I finally decided to commit."

Heitzman, a defensive lineman and tight end, said he pulled his commitment from Vanderbilt because of coaching turmoil within the program. Vanderbiltcoach Bobby Johnson and his staff received the commitment from Heitzman, however, Johnson retired following the 2009 season and was replaced by Robbie Caldwell. Caldwell resigned on Nov. 27, andJames Franklin was named the program's 27th head coach on Dec. 17.

Michigan hired Brady Hoke on Jan. 22 to replace Rich Rodriguez, who went 15-22 in three seasons.

Heitzman is the second central Ohio player to give Hoke a verbal commitment. On Jan. 20, Pickerington Central defensive back Tamani Carter became Hoke's first verbal commitment. Carter originally gave a verbal commitment to Minnesota.

The official signing date is Wednesday, Feb. 2.
