Known for keeping a stable coaching staff since becoming the head coach at Cincinnati, Mark Dantonio looked to shake up his coaching staff in late January when it was announced longtime defensive line coach Ted Gill would not return for the 2013 season.
Gill, who served as Dantonio's defensive line coach at Cincinnati and since coming to Michigan State, was well thought of by players and was the first coach not to leave the program for a head coaching position.
A couple of weeks later, Dantonio named 21-year coaching veteran Ron Burton as the Spartans new defensive line coach. Burton had spent the previous ten seasons in the same position with Air Force and wowed Dantonio during the interview process.
One thing that played in Burton's favor was the fact Dantonio felt his new defensive line coach would play a bigger role in recruiting.
Just a few weeks after the hiring of Burton, another change to the coaching staff took place as offensive coordinator Dan Roushar reunited with New Orleans Saints head coach Sean Payton, whom he worked with at Illinois in 1996 to become the Saints running backs coach.
Roushar, who took a beating by fans during the 2012 season as the offensive struggled, found the chance to move on to the NFL an opportunity he couldn't pass up.
By early March, Dantonio looked towards a close friend to help restructure his coaching staff with the hiring of former Ohio State assistant coach Jim Bollman.
Warner would have the primary role of calling the Spartans offensive attack, but Bollman's 36 years of coaching experience at the collegiate and professional ranks and Dantonio's level of comfort with a close friend, made the hire an easy one.
