25. Brian Sipe
Cleveland fans, look away now. The Raiders met the Browns in the 1980 playoffs in a game notorious for the play ‘Red Right 88.’ That was one of the most traumatic moments in the history of the Browns’ franchise, but it doesn’t tell the full story of the game. It shouldn’t have come down to a single play, and if Sipe actually performed well, it might have been a different story.

The league MVP threw 30 touchdown passes and threw for over 4,000 yards in a stellar season. At least, stellar right up until that postseason game. Sipe went 13 for 40 with three interceptions in one of the worst displays of his entire career. It was the wrong time to have a meltdown because the team depended on him playing at his top form. However, he tarnished the entire season with just one awful performance.
