Wiseman will stay behind Michigan's bench
Per George Sipple of the Detroit News, Brian Wiseman will continue in his capacity as a Michigan assistant coach under Mel Pearson. Billy Powers will not. FWIW, I've heard from various sources that Wiseman was doing yeoman work in a difficult recruiting situation the last few years; he's probably a good guy to keep around. I have not confirmed but suspect that he was the driving force behind Michigan's brilliant 2015-16 umbrella power play, as well.
Sipple has a list of potential second assistants for Pearson:
Some of the names in the mix to be next @umichhockey assistant are Chris Tamer, Bill Muckalt, Mike Komisarek, John Madden.

Madden is unlikely since he is an AHL coach who has a good shot at moving up to the NHL ranks in the near future. As previously mentioned, Muckalt is a USHL head coach/GM; I have no idea whether being an assistant at Michigan is a move up or down in terms of status. Some guy who seems to know what he's talking about on the USCHO message boards asserted that someone in Muckalt's role is probably pulling down 90-100k a year; Powers made 138k this year. Michigan can offer a major salary bump for him. Sipple had previously asserted that unless Muckalt was the new head coach at Tech he expected him behind Michigan's bench.
Tamer and Komisarek are both former Michigan defensemen who had long NHL careers. Tamer is currently an assistant for the USA women's team. Komisarek just retired from the NHL in 2014 and returned to Michigan to complete his undergrad degree; he was working with the team as a student assistant. Neither has the resume of Muckalt but both are very familiar with Pearson.
I'd imagine Steve Shields would stay on as the volunteer goalie coach since he goes way back with Mel and did great work this year with not one not two but three goalies.
As for Powers, this would seem to be a natural fit:
Billy Powers may be in the mix for vacant @USAHockeyNTDP head coach position. 1/2

That might not be as much of a recruiting boon as it seems. Most NTDP guys are already committed to a college by the time they join the program. Having Danton Cole around certainly didn't help MSU's recruiting efforts. But it can't hurt.
