The NFL Conference Championship Games kick-off today, with the New England Patriots going up against the Denver Broncos, and the San Francisco 49ers taking on the Seattle Seahawks. We've seen these games before: Peyton vs. Brady, and Carroll vs. Harbaugh. They're sure to be competitive match-ups, and you can definitely be certain that some heroes are going to be made. Will Russell Wilson be able to continue his upward ascension? Will Colin Kaepernick prove that last year wasn't a fluke? We can only wait and see. 

However, with the winners, there will also be losers. And when it comes to losing in sports, there's always that possibility attached to it that your team completely choked. You know what it looks like: Scott Norwood in Super Bowl XXV, Matt Hasselbeck throwing a pick-six to lose to the Green Bay Packers in the 2004 NFC Wild Card, and, most recently, the Kansas City Chiefs blowing a 28-point lead to Andrew Luck and the Indianapolis Colts. These moments are never pretty, but they happen. So, with two rounds of the playoffs still to go, here's a list of The Greatest Choke Jobs in NFL Playoff History, just to remind you of what could happen in the closing match-ups of the postseason. What choke do you think was the worst? Take a look at our list and let us know in the comments.
