Michigan State was swept by Michigan during the regular season, but it has a perfect record in conference title games. The Spartans' last championship came in a win over Ohio State in 2012.
The first half against Wisconsin was one of the best periods Michigan State has played all season.

Payne scored and Denzel Valentine hit a 3-pointer to give the Spartans a 26-15 lead. Then Dawson was fouled on a layup and made the ensuing foul shot.
Bronson Koening made a free throw for the Badgers before Payne and Travis Trice had consecutive three-point plays. Trice then forced a turnover and Harris scored on a fast-break layup to increase the lead to 21 with 5:39 left in the first half.
Wisconsin trailed 43-26 at the break, but it rallied in the second half. Dekker's dunk capped an 8-2 spurt that trimmed Michigan State's lead to 51-41 with 15:02 remaining.
The Badgers got within seven when Jackson made a pair of free throws with under four minutes to play and again when Jackson hit a 3 with 51 seconds remaining. But the rally fizzled from there.
Jackson finished with 10 points for Wisconsin, which shot 28 percent in the first half. The Badgers have dropped two of their last three games.
