Iowa State spent nearly all season rotating two quarterbacks.
The Cyclones finally gave option No. 3 a chance last weekend and third-stringer Sam Richardson responded with a brilliant night at Kansas.
Richardson, a redshirt freshman, completed 23 of 27 passes for 250 yards and four touchdowns as Iowa State (6-5, 3-5 Big 12) beat Kansas 51-23.
Richardson got his chance after starter Steele Jantz suffered a head injury in the first quarter.
Iowa State coach Paul Rhoads won't announce whether Jantz or Richardson will start the regular-season finale Friday against West Virginia (5-5, 2-5), but he did acknowledge Monday that Richardson has the edge for job.
