Five weeks ago, Michigan State played two games at Wisconsin. The first one didn’t go so well. The Badgers dominated, 6-0. The second game was competitive and the Spartans were in it late in the third period. But a 1-1 tie turned into a 4-1 loss, ignited by an untimely penalty which led to two power-play goals. With No. 5-ranked Wisconsin coming to Munn Arena this weekend, Michigan State’s challenge is to find a way to play the offensively powerful Badgers like it did in the “competitive” game” on Jan. 30.
