As for next year, MSU should take a step back, but who knows. The fact that MSU's lone Final 4 team in the last 6 years is probably the worst team they fielded in that stretch prevents me from dealing in absolutes. I'm assuming Bridges and Jackson are gone. Carter, Nairn and Schilling graduate. Rumors are Ward is sort of done, but I don't see any way he gets drafted. He's not what the NBA wants in a big anymore. We'll see if smarter heads prevail.
I would think they should still be a tourney team, anything beyond that is gravy. Off the top of my head, McQuaid was the only junior, so presumably 2019-20 should be a strong year.
With or without Wagner, next year Michigan should be the very heavy favorite.
