The way I see it, some people might have picked the Jaguars to be the "sleeper" team in the AFC South, but I think that "prize" should go to the Titans.  They have actually won a couple of games that they shouldn't have.  Let's take a look at the Titans' wins and losses.

Game 1 - Lose to the Raiders that were supposed to be good.  Raiders are 4-5.
Game 2 - Win against the Jaguars due to poor special teams play by the Jaguars.  Jaguars are 5-3
Game 3 - Win against the Seahawks.  Seahawks are 5-3
Game 4 - Lose big to the Texans (14-57).  Texans are 3-5
Game 5 - Lose to the Dolphins. Dolphins are 4-4
Game 6 - Squeak out a win against the Colts.  Colts are 3-6
Game 7 - Squeak out a win against the winless Browns in overtime.  Browns are 0-8
Game 8 - Win against the Ravens.  Ravens are 4-5

So looking at the wins, the Titans beat two teams with a winning record thus far (Jaguars and Seahawks).  Two other wins were close games with one of them going into overtime (against the Browns).

I don't really see the Titans as good at this point, more like lucky.
