The Big Ten coaching carousel has been nuts this offseason

When the Gophers started practicing this week, half of last season's coaching staff was elsewhere.

The shake up is part of a series of moves that see both of last year's hires, Corey Millen and Ben Gordon, move on to other jobs. Millen's stint as an undergraduate assistant ended when he stopped being an undergraduate. Gordon, Director of Operations, went back to the USHL to coach.

And that doesn't include assistant coach Grant Potulny moving up in the coaching world by becoming the third head coach in Northern Michigan history.

Gordon's job remains to be filled, but only head coach Don Lucia, associate coach Mike Guentzel and volunteer goalie coach Justin Johnson are back from 2016-17. Newcomer Scott Bell fills in Potulny's role.

Based on the rest of the conference Minnesota's turnover fits right in the Big Ten.

Michigan having a new head coach for the first time in over 30 years would be one thing. With two new head coaches in the conference, new coaching staffs, a new team joining and multiple cases of Ohio State assistants leaving for lateral jobs within the conference, the Big Ten coaching carousel has been a little nuts.

In several cases, the jobs are linked. Millen went to Air Force to become its Director of Operations, replacing Steve Miller, who went to Ohio State to replace Mark Strobel, who went to Wisconsin to replace Don Granato, who went to the NHL.

The full list is below.
