STILLWATER, Okla. (AP) — Only guaranteed one series, third-string quarterback Brock Purdy made it count and ended up playing the rest of the game for Iowa State.
Purdy completed 18 of 23 passes for 318 yards and four touchdowns, and also rushed for a touchdown, to help Iowa State beat No. 25 Oklahoma State 48-42 on Saturday.
A true freshman who had played just one series before this game, Purdy stepped in for Zeb Noland — who was starting his fourth straight game in place of injured starter Kyle Kempt — on the second series and immediately sparked Iowa State (2-3, 1-2 Big 12).
“I’m really proud of our football team today,” coach Matt Campbell said. “We told Brock that he’d play the second series and see what happened from there. I just thought there were some things that he could open up for us. I thought he did a really good job today. He’s a guy that has playmaking abilities.”
The Cyclones entered the day ranked last in the Big 12 in both scoring (17.5 points per game) and yards (299.5 per game) but reached season highs in both categories, amassing 465 yards overall.
With Iowa State missing leading rusher David Montgomery because of an upper body injury, Purdy also led the Cyclones in rushing. He had 84 yards, including a 29-yard TD run, on 19 carries.
“I think it forces another threat that (opponents) have to be ready for,” Campbell said about Purdy’s ability to run. “He gives you a little bit of everything. I think that’s important and it is certainly something that he brings to the table.”
Oklahoma State defensive coordinator Jim Knowles admitted that his team wasn’t sure what to expect when Purdy entered the game and Montgomery didn’t play.
“The first couple of series were three-and-out, so you thought, ‘OK, we’re going to get what we had planned for,’ and then we got a lot of things that we had not planned for,” Knowles said.
Tyler Cornelius was 19 of 33 passing for 289 yards and four touchdowns for Oklahoma State (4-2, 1-2), which lost its second consecutive home game. The Big 12’s leading rusher, Justice Hill, was limited to 66 yards on 24 carries, a 2.8-yard average. He did score a touchdown in his 12th straight game, setting a new Big 12 record.
“Our protections weren’t very good,” OSU coach Mike Gundy said. “We got into too many situations where we put pressure on Taylor and forced him to run out of the pocket. That was a big factor offensively, just not being able to protect and get the ball thrown down the field.”
