ISU defensive coordinator Jon Heacock will be the highest paid assistant coach under ISU football coach Matt Campbell, according to contracts released by the ISU Athletic Department on Friday. 

Heacock and new-passing game coordinator Jim Hofher’s contracts were released Friday through an open records request from the Daily. 

Heacock will make a base salary of $454,000 in 2016. He is signed through June 30, 2018 — the only assistant coach signed past 2017. He was officially hired on Jan. 5. 

Hofher, who will have a hand in coaching quarterbacks, will have a base salary of $235,000 in 2016. 

There were also a number of coaches who had their contracts amended. 

Tom Manning, the team’s offensive line coach and offensive coordinator, is the second-highest paid assistant coach and will make $350,000 in 2016. He is signed through June 30, 2017. 

Manning’s original salary of $250,000 per year was amended Jan. 1 when he was promoted to offensive coordinator. 

Running backs coach and assistant football coach Lou Ayeni, a holdover from former coach Paul Rhoads’ staff, saw his salary jump up from $191,900 in 2015 to $300,000 in 2016.

The following coaches also had their original contracts amended: Wide receivers coach Bryan Gasser from $150,000 to $175,000, tight ends coach/recruiting coordinator Alex Golesh from $210,000 to $215,000 and defensive backs coach D.K. McDonald from $175,000 to $200,000.

All of the assistant coaches will get 8.3 percent of their base salary if the team makes a bowl game. 

Campbell is reportedly making $2 million per year. His contract has not yet been released by the ISU Athletic Department.
