(AP) - Iowa State went through its first major staff change under fourth-year coach Paul Rhoads when offensive coordinator Tom Herman left for the same job at Ohio State.
The Cyclones stayed in-house by promoting Courtney Messingham to replace Herman, and they've kept the offense as simple and recognizable as possible this spring.
Iowa State wraps up its first spring practices with Messingham running the offense on Saturday with its annual scrimmage.
Rhoads said Tuesday that Messingham, who previously coached the tight ends and receivers, has done well handling the increased responsibility of running Iowa State's spread offense.
