When Dave Brandon resigned as Michigan's athletic director this week, the news did not come as a huge surprise.

There was one unexpected announcement, however, and that was the appointment of Jim Hackett as interim athletic director.

Hackett did not speak much at Friday's news conference, and it remains to be seen how long he'll be in charge and what major decisions he'll have to make, but the clock is ticking. Michigan's foundering football program was a major reason behind Brandon's dip in popularity, and the school will have to make a decision on coach Brady Hoke's future before too long.
