There is no denying what Mark Dantonio has done for the Michigan State Football program in the past 13 years. However, there are some questions at the time of his decision to step down as Spartan coach.

Dantonio announced his decision to retire on Tuesday a statement on Twitter,

"Today is one of the most difficult decisions I've ever made here in Michigan," wrote Dantonio. “First of all, I would like to thank our fans, alumni and our administration. Both former and current employees and especially our current and former players and coaches for all their support, hard work and dedication over the past 13 years. You really helped me make my dreams come true. "

The move took place less than a month after an additional $ 4.3 million retention clause in his contract paid him and less than a day before the national day of signing on February 5.

It also comes a day after a lawsuit brought up by former employee Curtis Blackwell alleging that the current coach broke the NCAA rules on a home visit and potentially uncovered violations related to a booster that “ Recruiting jobs / employment offers signing for MSU play. "

Last week, Dantonio's lawyer said all allegations of NCAA violations were "wrong".

Dantonio, who will continue to work in the MSU sports department, ends his career as the best Spartan coach with 114 victories, three Big Ten championships, a Rose Bowl win and an appearance in the College Football Playoff 2015.
