In 2006, Dantonio was hired as the Spartans head coach, returning to the school where he served six years as an assistant coach under Nick Saban and Bobby Williams.[2] Known as a defensive-minded coach, Dantonio has compiled a 100-45 record at Michigan State, giving him a .690 winning percentage, the highest of any Michigan State football coach since Clarence Munn, who coached the Spartans from 1947 to 1953.[3] During his tenure, the Spartans have won the school’s first bowl game since 2001 in the 2012 Outback Bowl and the school’s first Rose Bowl since 1988 in 2014. Dantonio’s Spartans hold active school record with four consecutive bowl wins. On October 8, 2011, Dantonio signed a contract extension that made him a “Spartan for life.“[4] In 2014, he earned the second highest salary among college football coaches, due largely to a retention bonus.[5]
