STATE COLLEGE, Pa. -- Michigan State will start a complete evaluation of its program on Monday morning following a 3-9 season that culminated with a 45-12 loss to Penn State here on Saturday night.

Spartans coach Mark Dantonio, though, has already decided that all nine of his assistant coaches will be returning next season.

"I'm not even considering letting any of our staff go," Dantonio said on Saturday night.

Dantonio was asked if any changes of responsibility are possible, and responded that "we'll look at what we do as a staff." He quickly added, though, that no staff members will be removed.

The Spartans coaching staff has come under fire as the program has slipped from 12-2 and the College Football Playoff to 3-9 this year.

The Spartans entered Saturday's season finale seventh in the Big Ten in total offense, seventh in total defense.

Of Dantonio's nine assistants, four have been on Michigan State's staff since his arrival in 2007: co-defensive coordinator and secondary coach Harlon Barnett, co-offensive coordinator and running backs coach Dave Warner, co-defensive coordinator and linebackers coach Mike Tressel and offensive line coach Mark Staten.

According to Michigan State, only two Division 1 schools have had more than five coaches on staff for 10 years or more.

Quarterbacks coach Brad Salem is on his seventh year on the staff, while wide receivers coach Terrence Samuel is in his sixth year. Defensive line coach Ron Burton and co-offensive coordinator and tight ends coach Jim Bollman are both in their fourth seasons.

The newest addition to the staff is linebackers coach and special teams coordinator Mark Snyder, who was added after former defensive coordinator Pat Narduzzi left to Pittsburgh.

The current staff has been intact in its current roles for the last two seasons. Barnett and Tressel added co-defensive coordinator duties before the 2015 season. Warner and Bollman became co-offensive coordinators in 2013.
