EAST LANSING — Michigan State’s offensive football coaches shuffled roles and responsibilities in the offseason.

They also enter the 2019 season with some reconfigured contract terms that could have them coaching for their jobs this fall, according to documents obtained by USA TODAY Sports Network.

MSU's five offensive assistants from last season, including new coordinator Brad Salem, signed amendments March 29 that reduced their contracts from two-year rollover deals to one-year rollover deals.

Quarterbacks coach Dave Warner, offensive line coach Jim Bollman, tight ends coach Mark Staten and defensive backs assistant Terrence Samuel were the other coaches who signed the amendment. Last season, Warner and Bollman were co-offensive coordinators, Salem coached quarterbacks, Staten coached the offensive line and Samuel coached receivers.

The amendments take MSU off the hook for any financial obligation beyond each single contract year for the five assistants, and comes on the heels of MSU coach Mark Dantonio deciding to reshuffle his offensive staff in lieu of hiring new assistants after one of the worst offensive seasons in his 12-year tenure.

The five assistants now must be notified between the end of the season and March 15 each year if the school intends to terminate their contract. Otherwise, their contracts automatically will be extended for the following season on April 1.

“There’s a lot of power in having the knowledge of what’s just occurred and how to fix it. And I’m banking on that being fixed,” Dantonio said at Big Ten media day in July, referring to the offense's role in last season's 7-6 finish. “Our coaches didn’t need to be motivated. I thought they handled the change like soldiers, and they went to work.”

Salem received a pay raise of more than $115,000 with his promotion to offensive coordinator and now makes $517,847, according to documents MSU provided to the Free Press in May. The other offensive assistants from last season did not receive raises. Warner ($516,924), Bollman ($498,462), Staten ($402,462) and Samuel ($387,693) have the same salaries from 2018.

“Sure, it’s difficult. I think it’s difficult for all of them,” Dantonio said in July. “But sometimes, you have to make decisions as the head coach. This was the possible solution I came up with. By doing it, I think that it was the best thing I could do. I mean, I just do.

“When you hire people that you don’t know, there’s a big unknown factor there. I know who is honorable. I know that these guys will work, and I know that these guys will care about their players.”

Warner and Staten came to MSU from Cincinnati with Dantonio in 2007. Salem arrived in 2010, Samuel in 2011 and Bollman in 2013. Bollman had worked as an assistant coach alongside Dantonio at Youngstown State under Jim Tressel, at MSU under Nick Saban and again under Tressel at Ohio State.

“I’m just trying to be a company man and do whatever the best thing I can for the whole crew,” Bollman said earlier this month, about the restructuring. “And I will continue to do that. My role happens to be changed a little bit. … I don’t know if we ever got to (the changes being) that big a deal, it was part of the overall picture.”

The amendments only impact the five offensive assistants from last season.

MSU’s returning defensive coaches — coordinator Mike Tressel, defensive tackles coach Ron Burton, defensive ends coach Chuck Bullough and defensive backs coach Paul Haynes — retained their two-year rollover deals and received raises. New receivers coach Don Treadwell, who swapped positions with Samuel, also received a raise and kept his two-year rollover deal after the former offensive coordinator rejoined Dantonio’s staff in 2018.

MSU had the nation's No. 1 run defense and No. 10 overall defense last season.

Still, the Spartans finished 7-6 after going 10-3 in 2017. The Spartans’ offense was among the nation’s worst last season and posted the lowest averages in scoring (18.7 points per game), total yards per game (342.1) and rushing yards per game (124.8) of Dantonio’s 12 seasons.

“It doesn’t take a sort of rocket scientist to say there were some areas of real strength and some areas where we need to get better,” athletic director Bill Beekman told the Free Press in May.

Dantonio’s base pay is $2,321,092, but his total compensation for the 2018-19 season was $4,390,417, according to a USA TODAY Sports salary study. He also got a $75,000 bonus for MSU making the Redbox Bowl last season.

Dantonio is on a six-year rolling contract that runs through Jan. 14, 2025. He is set to receive a one-time $4.3 million retention bonus Jan. 15, 2020 if he still's MSU's head coach.
