The lone holdover from Brady Hoke's coaching staff at Michigan is Greg Mattison.
Guiding the Wolverines' defense for four seasons as defensive coordinator, Mattison has now settled into his new role as defensive line coach under defensive coordinator D.J. Durkin and Coach Jim Harbaugh.
Through just two games, Mattison's guys have been as productive as any position group on the field. In those two games, the Michigan defense is holding opponents to a 17-percent conversion rate on third down, also coming up with three sacks.
"Well I think the second game against Oregon State we played more like we expect to play," Mattison said. "More effort and we've always prided ourselves here of everybody running to the football and getting to the football.
"In that game, I think the guys did that at a more consistent rate. We still have to get better at our technique. They hear that from me everyday and they're going to hear it until we grade out on technique like we should."
Mattison' top performer thus far is senior Chris Wormley.
Wormley is already credited with nine total tackles, a team high six tackles for loss, also coming up with a sack in Saturday's win over Oregon State.
"Chris has made some plays," Mattison said. "Chris has done some good things and there's a lot more good things to be had. He's got to keep striving to be as good as he can be.
"He's a very talented football player, he's got great size, great ability to run, he's strong and I'm looking for him every game, to get better."
After opening the season with a loss at Utah, Michigan took the field with high hopes against the Beavers in hopes of setting a tone and bouncing back from the trip to Salt Lake City.
Right off the bat, Oregon State proved uncooperative moving right down the field in seven plays to take an early 7-0 lead.
After that, Michigan's defense tightened up.
"There wasn't any panic," Mattison said. "You knew there was a breakdown here or there that caused it, you knew we were going to make the adjustments that we had on the sideline and D.J. does a great job with making sure he knows what's going on with all parts of it.
"He just got everyone together and said this is what happened, this is what we can't let happen and they adjusted to it."
Offering a unique perspective as the former defensive coordinator of this Michigan team, Mattison believes there one specific reason Durkin's approach is working so well early in 2015.
"It's been very good, sidelines after every play we're all together and D.J. will call the group together and explain exactly what and then we break down to each position," Mattison said.
"I think that's been good for both ball games and continuing to get better."
