Going into Super Bowl LVIII, the Kansas City Chiefs and defensive coordinator Steve Spagnuolo knew one thing about San Francisco 49ers quarterback Brock Purdy: Throughout the 2023 NFL season, Purdy had ripped opposing defenses to shreds when they blitzed him. Purdy had 101 completions in 150 attempts for 1,534 yards, 701 air yards, 15 touchdowns, two interceptions, and a passer rating of 128.6. The Chiefs had sent five or more pass-rushers on 208 opponent attempts, fourth-most in the NFL. And on those 208 attempts, opposing quarterbacks completed 112 passes for 1,122 yards, eight touchdowns, three interceptions, and an opponent passer rating of 76.2.
