A true classic is up next, courtesy of Leon Lett, the man with the dubious honor of having two of his plays in the top three of ESPN's "25 Biggest Sports Blunders" poll. Either of the two could have made this list, but this one takes precedence as it was in a Super Bowl, the biggest stage of them all.
Lett wasn't exactly known for his scoring prowess, having scored a grand total of zero touchdowns leading up to Super Bowl XXVII. But his time of glory was upon him as the game moved into its final quarter.
The Cowboys had already amassed a 52-17 lead when Frank Reich fumbled at the Dallas 35-yard line. Lett seized upon the loose ball and almost had the field to himself as he made his way to the end zone.
But when he got to the 10-yard line, he decided to watch some TV.
Determined to enjoy the moment for all it was worth, Lett slowed down to watch himself on the Jumbotron as he made his way past the goal line, throwing his right arm out and imitating Michael Irvin on the way to his first career touchdown.
What Lott failed to notice was Don Beebe chasing him down from behind with as much heart as you'll ever see in professional sports. Beebe arrived just in time to swat the ball from Lott's hand and out the back of the end zone for a touchback.
Lott never scored a touchdown in his career, but at least he failed in spectacular style.
