Per Bruce Feldman, Michigan is hiring another former Arkansas assistant:

For what is as of yet unknown. Rumors that Pep Hamilton and/or Tim Drevno are on their way out seem likely to come to fruition as a result of this, since Enos is another offensive architect type and not a recruiting-maven/position-coach sort.
Enos is a former MSU quarteback who entered coaching immediately after his playing career ended; since 1991 he's been a college coach. After bouncing around small schools for a decade he landed at Cincinnati as Mark Dantonio's QB coach and followed him to MSU for four years; he landed the head job at CMU in 2010. That didn't go that well—a couple of 3-9 seasons to start followed by .500 ball after—but he was something of a trendsetter in college football when he voluntarily left the CMU job to go be a P5 coordinator, joining Arkansas as OC in 2015.
His tenure through the lens of S&P+:

That's better than I expected in the SEC West; Bielema would probably still have a job if his defense hadn't cratered to the 113th this year.
Enos is a college guy whose most prominent stints as an assistant were at mashing pro-style programs, and he had good results despite working at a substantial talent disadvantage. College-lifer pro-style coaches are an endangered species, and while Enos doesn't have a Don Brown resume he's probably the best available coach who's at all a fit for what Michigan wants to do.
