It took the game's biggest stage to reveal Leon Lett's lack of intelligence.
The Dallas Cowboys had Super Bowl XXVII locked up. They were blowing out the Buffalo Bills.
They were about to pour it on some more when a Bills fumble was recovered by Lett, who had nothing but the end zone in his sights. As he was preparing to cross the goal line, he held out the ball in a show of celebration.
But Buffalo receiver Don Beebe hustled down and knocked the ball out just before he crossed the plane of the end zone. There was no touchdown for Lett, just embarrassment.
He was back at it again on Thanksgiving Day 1993.
In snowy Dallas, the Dolphins were lining up for a potential game-winning field goal. However, the Cowboys blocked the kick. As Miami players watched the ball roll in the field of play, Lett unbelievably came through and hit it with his legs. The ball then became live.
The Dolphins then bounced on the loose ball with just seconds remaining. That mind cramp by Lett gave Miami a second chance. This time, it connected on the field goal to win the game.
