14. Joe Gibbs
When a bad call happens during the regular season, it’s not that bad. A team can pick themselves up and move on. But all of a coach’s decisions in Super Bowls must be perfect. Otherwise, it will probably result in defeat. Some teams have never even reached a Super Bowl in their history so it is not an opportunity to waste. Unfortunately, Gibbs killed the Washington Redskins’ chances of winning against the L.A. Raiders in 1983.

The Redskins had an unbelievable offense all season but it didn’t click against the Raiders, who led 14-3 with just 12 seconds in the first quarter. Washington had the ball on their own 12-yard line. The safe option was to take a knee but instead, Gibbs called a risky screen pass. The Raiders intercepted it and scored a touchdown, putting the game beyond Washington.
