The Tennessee Titans are the favorites heading into their game on Sunday against the Houston Texans in Week 15. While that would have sounded crazy weeks ago, Vegas got this one right. Tennessee is the better team right now and has been playing better football.

Let's breakdown four reasons the Titans will beat the Texans and take control of the AFC South.

4. The Titans have remained consistent

Since the Titans have made the switch to Ryan Tannehill at the quarterback position, this team has established one thing that is important, consistency.

The Titans defense has also been consistent and over the last three games they haven't given up more than 21 points. This is a team that has been consistent on both sides of the ball, and with the confidence, they are playing with, the Texans are in trouble.

3. Texans lose shootouts, the Titans win

If you would have told Titans fans earlier this season that their team was going to win games because of their offense, they probably would be shocked. In each of the last four games, the Tennessee's offense has scored at least 31 points, so even if this game gets in a shootout, they can come away with a win.

For the Texans, their defense hasn't been great and they are coming off a game where they gave up 38 points to a Drew Lock led Denver Broncos squad.

The Texans' defense isn't known as elite, but to let a rookie quarterback making his first start on the road throw all over the field is embarrassing. Even if the Titans' defense struggles, it won't put them out of a position to win the game.

2. Derrick Henry

If Derrick Henry was playing for the Dallas Cowboys or New England Patriots, he would be talked about as being one of the best running backs in the league. Since he plays for the Titans,  he isn't getting the attention he deserves.

On the season, Henry has rushed 250 times for 1,243 yards and 13 touchdowns. Against the Raiders in Week 14, he rushed 18 times for 103 yards and two touchdowns.

In the Texans' last game, they allowed Phillip Lindsay and Royce Freeman to rush 24 times for 75 yards. Houston's defense hasn't been great, so allowing only 75 yards would be considered a win for them.

They aren't going to get so lucky in this game and Henry is going to run wild again.

1. Ryan Tannehill

Ryan Tannehill was signed in the offseason to be a backup for one season in case Marcus Mariota got hurt. Mariota never got hurt but it now looks Tannehill is not just the starter for the rest of the season, but he could be the long-term option going forward.

On the season, Tannehill has thrown for 1,993 yards, 15 touchdowns, and only five interceptions while completing 73.4 percent of his passes. Against the Raiders in the Titans' last game, he threw for 391 yards, three touchdowns, and one interception.

The Texans are coming off a performance where they got lit up by Drew Lock and there is no reason Tannehill won't do the same thing. Tannehill is going to have another big game and lead the Titans to a big victory. After Sunday, the Tennesee will be sitting in first place all by themselves in the AFC South standings.
