Penn State’s offense didn’t show enough improvement in 2015.

That’s why the school announced on Sunday that it fired offensive coordinator John Donovan.

James Franklin’s assistant had been on staff with him in Happy Valley for two seasons, and the two worked alongside one another at Maryland and Vanderbilt, as well.

The Lions finished the season with their worst loss of the year in East Lansing on Saturday, one in which the offense was held to just 16 points for the second straight week.

Against the likes of B1G East powers Michigan, Michigan State and Ohio State, Penn State averaged just 14 points per game. They finished 108th in FBS in total offense, and allowed more sacks than any team in the B1G.

Penn State finished the season with eight wins, but none of which came against top-25 teams.

Christian Hackenberg still hasn’t officially announced whether or not he’ll be returning to Penn State or forgoing his senior season to enter the NFL draft. Penn State’s new offensive coordinator could have a new quarterback to built his system around if Hackenberg were to leave for the NFL.

The search for Donovan’s replacement will begin immediately.
