Beilein still has some talent coming back next season (LeVert, Walton, Irvin, Albrecht), but his coaching chops will be tested again next season. Losing 3 underclassmen to the draft doesn't happen very often, unless your name is Kentucky.
Still see Go Blue finishing nowhere lower than 5th in the B1G next season, but losing Stauskas/Robinson/McGary I'd certainly jump Ohio State and Michigan State ahead of Michigan into the top 3 at this point. McGary should be the last of the Big Ten early NBA declarations. With Michigan losing all 3 of those guys, my Big Ten top half (pre-summer) would be:
1. Wisconsin (clear favorite)
2. Ohio State (best of the rest)
3. Michigan State (still plenty of talent returning)
4. Michigan (a nod to Beilein's coaching acumen, and the key players coming back)
5. Iowa (cupboard far from empty despite loss of Marble; this seems like a safe spot after season-ending crash)
6. Illinois (gambling Illini will be significantly better offensively)
7. Nebraska (will be tough to repeat 2013-14, even with most everyone back)
Good list but our Gophers will be booting one of those teams out of the top 7.
