B1G basketball is always overrated. They play circa a 1990 big men basketball and mange to consistently under achieve.
I know it's easy to say this, but since 2001—a year after Michigan State won the last NCAA for the conference— they've tied the ACC for most Final Four participants (14) and are second in title game appearances (7 vs. 9 for the ACC). They also have had the most
different teams appear in the finals (6) over that time. As a conference, they certainly aren't underperforming...and if I went a year back, they get a title and pass the ACC on Final Four appearances. And if I go two years back, that gap widens.
