A little biased, but a team with three playoff wins on the road preceding perhaps what may be the greatest upset in Superbowl history kind of cements Best Sports Team status in my book. The New York Giants went against the critics' odds and prediction to win at Tampa Bay, win at Dallas(!), win at Green Bay(!!) and then the ultimate football figurative giants, the New England Patriots (!!!). To follow then miraculous playoff season by defying more critics and clinching the NFC's number one just solidify their place amongst the greatest calendar year in the NFL.
