Per Chris Vannini, Michigan's filled a hole they don't appear to have:

Michigan: Alabama co-offensive coordinator / wide receivers coach Josh Gattis will be named offensive coordinator at Michigan, people with direct knowledge of the situation tell The Athletic’s Chris Vannini and Bruce Feldman. Gattis spent one year at Alabama and previously worked at Penn State. At Alabama, Gattis directed one of the top wide receiver groups in college football.

Compounding the oddity here is that Maryland hired him three hours ago.

Gattis is a 34-year-old who played safety at Wake Forest and had a cup of coffee in the NFL after being drafted in the fifth round. Before Alabama hired him away to be the WR coach and co-offensive coordinator—whatever that means—he'd been James Franklin's WR coach at both Vandy and PSU. Mike Locksley, the other co-OC, took the Maryland job and was apparently set to bring Gattis along before this abrupt about-face.

[After THE JUMP: I'm just warning you there is a picture of Allen Robinson but now we can feel good about it!]

Saban on Gattis, FWIW:

“Josh is a very, very good coach,” Nick Saban said in October “He’s a very bright guy. He has been in some good systems. He has a good understanding of the big picture offensively. He’s very technical in terms of how he coaches and teaches his players and he’s got a really good personality.

“He can confront guys when they are not doing things the way they are supposed to do them, and I think that has created a lot of consistency in our receivers and improved their toughness. We have some good players and he has got them playing well.”

Pros: Gattis is highly sought, having bounced from PSU to Alabama and then getting intercepted beforehand. PSU's WR corps was excellent for the duration of his tenure…

…and dropped off significantly after he left. The Alabama WRs were part of the most explosive passing offense in college football this side of Kyler Murray, and to whatever extent he co-OC'd said offense that's good. Given Locksley's track record and Gattis getting to asborb some of Joe Moorhead, chances are good that he had a major say.

Also, Gattis has the requisite recruiting rep:

On top of his coaching efforts, Gattis was also viewed as one of Alabama’s top recruiters. He helped the Crimson Tide land five-star defensive lineman Antonio Alfano as well as four-star receiver John Metchie and four-star defensive lineman Justin Eboigbe in this year’s class.

And he's definitely played Madden and can only hope with the whole "maybe play fast sometimes" thing.

Cons: last year's Alabama offense was his only year with any kind of coordinator title. There are probably dozens of coaches who could have lit up college football with Tua Tagovailoa and friends. Also… if you're Alabama why not just bump him up to OC and keep him? Going to Michigan is one thing. Maryland?

This is kind of a swing in the dark but Gattis is the hot name and sure why the hell not. There is now another shoe to drop: unless Michigan plans on dropping a defensive assistant—highly unlikely—this presages an exit or reassignment from the offensive staff. Pep Hamilton has been interviewing and spotted at some NFL games and seems like the most likely departure.
