The real competition for the sixth spot in the playoffs is between the Bengals and the Titans. The Steelers are shoo-ins, and the Titans own the tiebreakers against everyone else except the Bengals.
Both squads are likely to get two more wins. The Titans will beat the Jaguars and the Colts before facing the Texans, and the Bengals will win against the Rams and Cardinals before taking on the Ravens.
Similar seasons, eh? The Titans need to beat the Texans, in Houston, to get to 10 wins. They then need the Bengals to lose to the Ravens. If either of those things doesn't happen, the Titans will be watching football in January, not playing.
It may come down to what the Texans do. Houston may be the third seed at the end of the season, meaning that they'll be playing whichever squad (the Bengals or the Titans) that gets in on the last playoff spot.
Even if they're too good for the Titans to handle, they may rest their starters to avoid injury and give the Titans an easier time before they face them again in the first round of the playoffs.
If Cincinnati beats Houston next week, that's it for the Titans. So...go Texans, I guess.
