Michigan–Michigan State men's ice hockey rivalry The Michigan–Michigan State men's ice hockey rivalry is a college ice hockey rivalry between Michigan Wolverines men's ice hockey and Michigan State Spartans men's ice hockey that is part of the larger intrastate rivalry between the University of Michigan and Michigan State University. The rivalry between the Spartans and Wolverines notably includes football and basketball rivalries, although it extends to almost all sports and many other forms of achievement. The most notable examples of the hockey rivalry are two outdoor games, the October 6, 2001 Cold War in East Lansing and the December 11, 2010 Big Chill at the Big House in Ann Arbor, which set the world record for attendance at a hockey game. This record however was broken four years later at the 2014 NHL Winter Classic on January 1, 2014. As of 2013, both teams are members of the Big Ten Conference, although they have previously competed together in both the Central Collegiate Hockey Association (CCHA) and the Western Collegiate Hockey Association (WCHA).
