LB Junior Colson announcement that he is leaving the wolverines now another significant issue for the Team….

The Wolverines are still in the upper echelon of college football in terms of total defense — meaning, yards surrendered per game — but 2018 and 2019 have seen some serious lapses, particularly against Ohio State. Still, the maize and blue have finished no worse than No. 11 in that metric since Jim Harbaugh arrived, but there has to be a reason why it hasn’t been able to keep pace with the Buckeyes, right?

One part of it certainly could be the lack of push up front. In 2016, Michigan had eight sacks against OSU. In 2017, it had three. But in 2018 it had zero and managed just one in 2019.

So to say that the defensive line needs to improve, particularly in that game, it wouldn’t be terribly novel of an idea.

Thankfully, it appears that’s the defense’s strength heading into 2020, as Harbaugh told Jon Jansen on the Inside Michigan Football radio show that he feels the defensive front is that side of the ball’s identity — starting with the two ends up front.

“I think if you can picture – I know you can picture it, but Kwity Paye and Aidan Hutchinson – two — wow,” Harbaugh said. “Tremendous players and they’re having great camps. I kinda look over at them and I see the identity for our defense in those two. Really talented, great, high-effort kind of players. Carlo Kemp and Chris Hinton – and now Donovan Jeter also is really surging and doing great. Such a natural and good football player. And Jess Speight, total Michigan man. Talk about position switches and a guy who will do anything for the team — In there playing nose.

“Also, Luiji Vilain, looking for him to have a very good year. Taylor Upshaw is surging as a player. Also say Julius Welschof, keep an eye on him. He’s coming into his own. Mike Morris, Mazi Smith, Gabe Newburg – really turning into great football players.
