ANN ARBOR, Mich. -- Although Michigan's defense is in the process of learning a new scheme under defensive coordinator D.J. Durkin, the Wolverines are privy to some familiarity within its coaching staff.
Formerly the defensive coordinator under Brady Hoke, Greg Mattison stayed on Jim Harbaugh's staff to coach the defensive line, a unit that could be in line for big improvements this fall.
But the most talked about player on that Michigan defense during spring practice has been former cornerback turned safety, Jabrill Peppers, who is making his presence felt all over the field.
Josh Newkirk and Kyle Bogenschutz offer thoughts on the Michigan defense this spring with just 10 days remaining until the Apr. 4 spring football game at Michigan Stadium.
