Indiana coach Mike Woodson questioned his team’s toughness after the Hoosiers dropped their fourth consecutive game, damaging their sagging postseason hopes.

Woodson said postgame he has no explanation for why the Hoosiers lacked energy early. And while Indiana’s defensive struggles in the opening several minutes were illuminated by perimeter shots, its issues stemmed from the interior with junior forward Malik Reneau and sixth-year senior center Oumar Ballo.

Since Indiana earned a 77-76 overtime win at Ohio State on Jan. 17, it’s been a two-week downer. The Hoosiers lost (after leading) at Northwestern on Jan. 22. They also lost (after leading in the final minute) against Maryland Sunday at Simon Skjodt Assembly Hall.

Indiana basketball couldn't overcome a horrific start against Wisconsin, here are player ratings from the Hoosiers' fourth straight loss:

Tuesday night’s loss in Madison was the loss Indiana fans had been fearing would come. A superior opponent came out and asserted itself before the desperate Hoosiers had any chance in the game. The Badgers had eight points before Indiana scored.
