But are the boys in Big D the biggest disappointment of the year? They've certainly got plenty of competition.
Carolina Panthers — Not much was expected out of this team, but by virtue of having the worst record in the league, they make this list.
Cincinnati Bengals — The pairing of Terrell Owens with Chad Ochocinco turned out to be a nightmare for Carson Palmer.
Dallas Cowboys — Their quarterback broke his collarbone and their coach was fired. But hey, at least Jerry Jones was entertaining on Entourage, right?
Denver Broncos — Tim Tebow has been the lone bright spot for a team at 4-11 that fired its coach and, even with a win on Sunday, will finish with its worst record since 1990 (5-11).
Houston Texans — Perenially labeled a contender in the summer, the Texans are 5-10 and lost eight of their last nine games.
Miami Dolphins — The dark horse to win the AFC East, the Dolphins lost in consecutive weeks to the Jets and Patriots in Miami by a combined score of 72-37. And so ended their playoff hopes.
Minnesota Vikings — The Vikings had to beg Brett Favre to come back, and they're probably sorry they did.
San Francisco 49ers — To be in the NFC West and not even be a playoff contender is an indictment on the San Francisco organization. A shouting match with quarterback Troy Smith was a fitting end to Mike Singletary's tenure as head coach.
Tennessee Titans — This team acquired Randy Moss and proceeded to make him look like a nobody.
Washington Redskins — Many pegged the Redskins to compete for the NFC East crown in 2010. Instead, there was just a whole lot of drama between Mike Shanahan and Donovan McNabb.
