Seattle Seahawks (2014)
Pete Carroll allowed one of the worst calls in Super Bowl history when the Seahawks lost in 2015. In short, they passed when they should have won the ball. Seattle was at New England’s one-yard line and had one of the most effective running backs in the league. Instead, Russell Wilson threw the ball to Ricardo Lockette.
Malcolm Butler intercepted the pass and New England won the game. Seattle fans couldn’t believe what they witnessed. Carroll insists that they made the right call statistically but it remains one of the most infamous decisions in NFL history (via Sports Illustrated).
