Coach Harbaugh speaks with the media at Thursday's press conference.

Jordan called Harbaugh a few weeks ago in an attempt to convince him that the Michigan football team should wear his Jordan Brand Jumpman clothing. His efforts were successful: The Wolverines will be the first college football team to wear the Jumpman logo beginning in the 2016 season.

But with just 10 days before the Wolverines’ season opener at Utah, Michigan defensive coordinator D.J. Durkin is eyeing the next step in improving a defense that was already among the best in the nation last season: versatility.

In a practice open to students at Michigan Stadium, Jake Rudock and De'Veon Smith took the bulk of the first-team reps at quarterback and running back, respectively.

Drake Johnson runs through an arm tackle against Indiana last year. Johnson has almost fully recovered from an ACL tear he suffered late last season.

After climbing half a dozen rungs on the depth chart, coming back from an ACL tear, then averaging a team-high six yards per carry on a dismal offense last season, no one would discredit Johnson for walking away from football. But instead, he wants to do it all over again.

Thursday evening, the hall-of-fame basketball player announced that the Wolverines would become the first football team to wear Jordan brand apparel, joining the men’s and women’s basketball teams’ switch to the provider in 2016.

De'Veon Smith runs up the middle against Appalachian State last season. Smith, Ty Isaac, Derrick Green and Drake Johnson are competing for the starting job this year.

Senior Drake Johnson and juniors Derrick Green, De’Veon Smith and Ty Isaac are all entering at least their third year of collegiate play, and all four have been the go-to guy in important minutes.

And while conference media days are often known to be haphazard affairs, Harbaugh was in seemingly unchartered territory with the interest media members took in every facet of his life and career.
