Last season, the AFC South sent two teams, the Colts and the Texans, to the playoffs. While both teams have shown some flaws, they appear to still be among the league's best.
Meanwhile, the Jacksonville Jaguars seem to be the league's absolute worst, and it isn't even close.
Then there are the Tennessee Titans, who have quietly matched the 2-1 record shared by the Texans and Colts, and who may be on the verge of putting together their own surprising playoff run.
The Colts Defense Is Better Than We Thought
During the Colts' shocking playoff push in 2012, virtually all of the attention was given to then-rookie quarterback Andrew Luck and the Indianapolis offense.
After all, the Colts defense (ranked 26th, allowing 374.2 yards per game) was far from a dominant unit.
However, Indianapolis has shown dramatic improvement early this season, ranking 15th in defensive yardage (341.3 yards per game) and seventh in scoring (16 points per game).
The defense was a major force in the Week 3 win over the 49ers, limiting San Francisco to just 14 first downs and a mere seven points.
The Jaguars Are Not
No one had exceptionally high expectations for the 2013 Jacksonville Jaguars, but this team has been painful to watch.
Not only does the team rank dead last in offensive yardage (230.3 yards per game) and scoring (9.3 points per game), but it also ranks near the bottom in scoring defense (30th at 30.7 points per game allowed).
The quarterback situation surrounding Blaine Gabbert and Chad Henne is a complete mess (with one touchdown and five interceptions to show for it), and the rushing attack (52 yards per game) isn't much better.
Jake Locker Is Coming into His Own
The 2-1 Titans have been one of the most underrated surprises of the early 2013 season.
The play of third-year quarterback Jake Locker has been another one.
Locker's first two seasons were anything but impressive, and the pressure is firmly on for him to prove something this year or be passed over for a quarterback in next year's draft.
Fortunately, Locker has responded to the challenge, providing two wins and taking the division-rival Texans into overtime in the team's lone loss.
Locker's numbers haven't been overwhelming (572 yards passing, 81 yards rushing and four total touchdowns), but he is winning games and has yet to turn over the football.
If Locker can continue to progress and keep his team in contention, the Titans may finally decide he can be their quarterback of the future, which was far from a sure thing heading into the season.
