Brock Purdy

QB · Iowa State · Sr · #15

Picks you apart underneath and protects the ball. Four seasons in the Iowa State quarterback room to date. All-Big 12 in 2021 made it three straight seasons on the honors list. A game that shows it: 356 passing yards and 34 rushing yards against Texas Tech — Week 11, 2021.

High-percentage passer who protects the ball. Loses the matchup on improvisation.
