There have been players throughout NFL history who have played perhaps the largest roles of any individual player on their respective teams when it came to upsets over heavily-favored teams.
An example of a player to accomplish this more recently?
When you factor in his model of work thus far at this point in his career, he has recently led the Giants to the Super Bowl with two consecutive road victories over the two best teams in the NFC conference, the Green Bay Packers and the San Francisco 49ers.
The Giants entered Lambeau Field as seven point underdogs and came out of it with a 37-20 victory, in large part, due to Manning outperforming Aaron Rodgers to the tune of 330 yards and three touchdowns.
New York also managed to enter Candlestick Park and defeat the No. 2 seeded San Francisco 49ers 20-17 in overtime. Manning threw a lead-changing touchdown pass to Mario Manningham halfway through the fourth quarter to give the Giants the score that they needed for a chance to win it in overtime.
Along with Manning, there have been several other notable greats in the past who have been giant slayers of their own.
Just who are those players?
