This one still sticks in the craw of most Patriots fans. In the 2001 AFC Playoffs, Tom Brady lost a fumble with 1:47 left that ended up sealing the game for the Raiders, who ended up beating the Steelers in the AFC Championship before falling 20-13 to the St. Louis Rams in what turned out to be Kurt Warner's penultimate Super Bowl victory.
I wonder how things would have been different had the referees called the fumble the other way. Pats fans swear his hand was moving forward and that the 'tuck rule,' which would have ruled it an incomplete pass, should have been called. I know Brady has a reputation for theatrics and comebacks, but that was a long shot of turning into anything.
I wonder how Brady would be seen today if he had pulled that off.
