Some stunning news came out of East Lansing on Tuesday afternoon, as Mark Dantonio announced in a statement that he would be stepping down as head coach at Michigan State after 13 seasons with the program.

Many speculated that the 2019 season might be Dantonio’s last as the head coach, but he continually reiterated that he planned to continue coaching the Spartans in 2020. The timing was surprising, though, as Dantonio made the decision just one day before National Signing Day.

A good chunk of Michigan State’s 2020 class had already signed their Letters of Intent.

Dantonio leaves Michigan State as the program’s all-time winningest coach, guiding the program to 115 wins in his 13 seasons. He also led the Spartans to 12 bowl games, three B1G titles and one College Football Playoff appearance.

Below are the reactions to Dantonio’s surprising announcement:
