Iowa State defensive coordinator Jon Heacock says the recipe for success will remain the same even though many of the faces have changed. The Cyclones lost several veterans on defense, including safety Greg Eisworth and former Big 12 Defensive Player of the Year Mike Rose at linebacker, off of last year’s team that finished 7-6.

Heacock hopes new leaders emerge during spring drills.

Heacock expects veterans like defensive end Will McDonald and linebacker O’Rien Vance to step up.
