Ohio State didn't just keep itself alive for a piece of the Big Ten title, which would be its fourth in a row.
Michigan State, Wisconsin and Michigan all remained within striking distance thanks to Indiana's loss. While the Badgers and Spartans face an elimination bout on Thursday, Michigan controls its own destiny. What's more, all five potential contenders play their season finales on Sunday.
If no one slips up on Sunday, a Michigan victory would cause a four-way tie atop the conference. The four teams would all receive first-round byes at the Big Ten tournament, and the largely ceremonial top seed could be the main element up for grabs in Ann Arbor.
The conference's primary tiebreaker is head-to-head winning percentage, and the Wisconsin Badgers are the only team that could top Indiana.
Each contender's current record against the other four:
Ohio State 4-4
Michigan State 2-4
Michigan State's win over Wisconsin is not included, since one will no longer be a contender after Thursday, forced into a first-round game in Chicago.
Of course, Indiana can make it all a moot point with a victory. The Hoosiers are still in control for their first outright Big Ten title since 1993.
The crowded top of the Big Ten table underscores the brutal difficulty of this conference race. In a chaotic season, it's only appropriate that the nation's best league take its race down to the final day.
