DES MOINES, Iowa (AP) — Iowa State coach Paul Rhoads says sophomore quarterback Sam Richardson will start this week’s game against No. 19 Oklahoma State. The Cyclones initially listed Richardson and freshman Grant Rohach as co-starters against the Cowboys. But coach Paul Rhoads says Richardson will get the starting nod on Saturday.

Rhoads says Richardson’s knowledge of Iowa State’s offense was a key factor in that decision. Rhoads adds that Richardson needs to make smarter decisions and quicker judgments. Richardson, a redshirt sophomore, has started all six games for the Cyclones (1-5, 0-3). He has thrown for 1,255 yards and 10 touchdowns.
