Michigan football mailbag: Defensive front, Harbaugh's leash, offseason review and more

In a wide-ranging mailbag episode, we discuss a number of key topics that the Michigan faithful are curious about as the program enters the summer.We begin with a look at Michigan's front seven, and where things stand after the Wolverines lost out on USC DT transfer Jay Toia. We discuss why Michigan's defensive line might be in trouble, but also how we're hearing that the linebacker room's situation may be more dire. We identify players who could change that narrative, as well as what position groups might be limited in their impact this season.We then turn to the ever-popular question about Jim Harbaugh's leash at Michigan. We discuss why the Wolverine coaching staff's leash might not be as long as the contract extension suggests, what it would take for Harbaugh to be fired, what to make of Harbaugh's offseason changes both in the coaching staff and recruiting staff and more on where things stand.During the 80-minute episode, we also look at Alan Bowman's potential in the quarterback battle, what stage of grief Michigan fans seem to be in, how our view of offseason rumors have changed and plenty more.
