EAST LANSING, Mich. (AP) - Notre Dame and Michigan State have decided to play each other less frequently in football. Michigan State athletic director Mark Hollis says he and Notre Dame athletic director Jack Swarbrick agreed their current contract is challenging because of conference games each school has to play every season. The Fighting Irish will begin playing games against Atlantic Coast Conference schools this year. The Spartans will play nine games in the Big Ten each season starting in 2016. Notre Dame and Michigan State were scheduled to play each other in four straight seasons followed by two-year breaks through the 2031 season. Hollis says he expects games at Notre Dame in 2016 and 2026, at Michigan State in 2017 and 2027, plus a pair of neutral-site games.
