ANN ARBOR -- There's been plenty of change when it comes to the Michigan football team's offensive coaching staff in recent months.
Jim Harbaugh watched his tackles and tight ends coach, Greg Frey, depart for Florida State. A hire backfire on him and depart for Alabama. Then one of his long-time confidants, Tim Drevno, abruptly left in early March.
The net result has been three new additions and, presumably, a new look to the Michigan offense. But what does that mean for the play calling moving forward?
Harbaugh hasn't figured that out yet.
"Well, I haven't decided," Harbaugh said Friday, after Michigan's first spring practice.
