Michigan radio analyst/former NFL offensive tackle Jon Jansen was a guest on Glenn Clark Radio Friday.
Among the topics he discussed were:
-If Mike McDonald’s decision to leave for the Ravens’ Defensive Coordinator job says anything about Jim Harbaugh’s future
-What we can expect schematically from a Mike McDonald defense
-How McDonald was able to improve Michigan’s defense so drastically and quickly
-Could McDonald’s age (34) be any sort of impact in the NFL?
-The possibility of McDonald re-uniting with edge rusher David Ojabo, a potential Ravens NFL Draft target at #14
