The NFL season has been a pretty interesting one. No one expected the Denver Broncos to be undefeated through their first five games, nor did they expect the Cincinnati Bengals to start out the season with 4 wins in 5 games, including one over the Pittsburgh Steelers. The Cowboys look weaker than usual, as do many other teams too. Let's take a look at some of the biggest underachievers through the beginning of the 2009 NFL season. With some luck, any of these teams still has some time to turn things around - the clock is ticking though.

First of all, the Carolina Panthers coasted through the 2008 regular season on the strong play of Jake Delhomme, Steve Smith, and DeAngelo Williams. Many saw them as a favorite to win the NFC last season, and they ended the season with a playoff loss to the Cardinals, but still had a great year by all accounts. The beginning of the 2009 season has been anything but a follow up to their success in 2008, as the team has dropped 3 of its first 5 games and doesn't show many signs of improvement.

The other big disappointment in 2009 thus far has to be the Tennessee Titans. The Titans won the AFC South division with flying colors in 2008, and their defense was amongst the best in the NFL. The running back duo of Chris Johnson and LenDale White was nearly just as good. Somehow, the Titans are still winless in 2009, and a trouncing at New England was even worse for the team's prospects.
