In 2008 the New England Patriots were the undisputed best team in football. They went into the Super Bowl 18-0 (16-0 regular season) and had arguably a top 3 quarterback of all time. The New York Giants had a young quarterback who most people at the time only knew because of his older brother. It truly was a David vs. Goliath situation and just like in the history books David won.
This year you could make an argument that the Pittsburgh Steelers were the best team in football. You could also safely say that nobody saw the Arizona Cardinals getting to the Super Bowl, or even out of the first round. But they did.
The Pittsburgh Steelers looked to embarrass the Arizona Cardinals getting off to an early 20-7 lead. Behind Kurt Warner and the best receiver in football Larry Fitzgerald the Cardinals wrote history with the biggest comeback in Super Bowl history taking a 23-20 lead.
The Steelers looked to be out until a freak pass got the team in field goal range. Another pass, reminiscent of Matt Cassel's amazing toss to Randy Moss in Foxborough to force overtime with the Jets, Ben Roethlisberger hit Santonio Holmes and the team regained a 27-23 lead. Kurt Warner searched for a miracle on a drive that could take no longer than 35 seconds for Arizona to win. But a fumble changed everything and the Steelers were victorious yet again.
This was an electric game and despite none of the "popular" teams like the Cowboys, Patriots, Giants and Jets appearing fans picked a side and strongly stayed there until the end. It was a game of momentum switches, but in the end with their backs against the wall Pittsburgh prevailed.
No game may ever match the epic Giants/Patriots clash of 2008, but this was a great conclusion to a phenomenal season.
