After sitting out a season - and playing church league flag football to stay in shape - Park transferred to Iowa State last season. "When you do that to a team that has their backs against the wall - we know exactly how it's feels - it's something that you can't do". He became the first Iowa State player since Dave McCurry in 1971 to get significant action playing both ways in a game, according to the Des Moines Register. The Cyclones took the lead for good on Kyle Kempt's 25-yard touchdown pass to Allen Lazard with 2 minutes, 19 seconds remaining. The quarterback-turned-linebacker played on both sides of the ball against the Sooners after starting QB Jacob Park didn't make the trip because of a health issue. Baker Mayfield passed for 306 yards and rushed for 57 the Sooners (4-1, 1-1), but his Heisman hopes and Oklahoma's College Football Playoff took major hits. The converted quarterback had 20 tackles last week against Texas, the most for any Big 12 player this season.
Iowa State came into this game on 0-17 skid against ranked opponents, dating back five years and a day since they visited No. 15 TCU and beat the Horned Frogs 37-23.
After scoring on its first four drives, Oklahoma came away from the next four drives with no points, letting the Cyclones back into the game.
For Iowa State, this was a monumental triumph, among the greatest in program history.
The move mimicked what Mayfield himself did at Ohio Stadium earlier this season when he planted an Oklahoma flag in the middle of the block "O" at midfield.
Iowa State rallied to tie the game in the second half. Sooners RB Abdul Adams and WR CeeDee Lamb left the game in the first quarter with injuries.
