Chris Cosh is headed to the Univeristy of South Floida to coach its defense.
The school announced the hire Wednesday night, leaving Kansas State to find a new defensive coordinator.
Cosh coached the Wildcats’ defense the last three seasons and spent five total seasons working under coach Bill Snyder at K-State.
Cosh, who will coach the linebackers as well at South Florida, worked with USF coach Skip Holtz at South Carolina from 1999-03 as assistants.
At K-State, Cosh’s defense had their share of problems, ranking 119th nationally against the run in 2010 and 105th overall.
This past season, K-State’s defense improved some under Cosh, ranking fifth in the Big 12 and 72nd overall, as the Wildcats won 10 games — losing to Arkansas 29-16 in the Cotton Bowl.
With his move to the Big East, Cosh has now been a defensive coordinator in five of the six BCS conferences.
