Iowa State does return a starting quarterback, though sophomore Sam Richardson didn't take over until the final three games last season, when he threw eight touchdowns with only one interception.
What the Cyclones will really miss are Jake Knott and A.J. Klein, the standout linebackers who had been such a force in the Big 12.
"You don't replace those guys. You don't replace them from a leadership position. You don't replace them from what they've meant to our era of Iowa State football," coach Paul Rhoads said.
