I can make a case that Jeff Feagles is personally responsible for our 2007 Super Bowl win.(i know its a stretch but its funny anyway)
In 2005 David Tyree made the probowl as a special teamer, not for his returns but mostly because of him downing a great number of punts inside the 5 yard line. Not saying he didn't do a great job but Feagles was killin it that season and just putting them right there for the downing. I think a lot of players could have did what Tyree did that season with the way Feagles was punting. That season is what earned Tyree the label of special teams ace, and it was his special teams play that kept him on the team, he was never exactly lighting it up at the WR spot.
Flash forward to 2007 and the greatest play in superbowl history, without that play the giants probably do not win the superbowl, so there you have it. Jeff Feagles is singlehandedly responsible for the Giants 2007 Super Bowl win.
