With just four games remaining in the season, the Houston Texans head to Nashville to play a must-win game against the Tennessee Titans.

The Titans are coming off a big upset victory over the Miami Dolphins, and the Texans are fresh off an embarrassing loss to the New York Jets.

Making matters worse, CJ Stroud is in concussion protocol, which will likely force Davis Mills or Case Keenum to make the start for the Texans.

With that in mind, which backup quarterback should the Texans trust the most?

Davis Mills has played more football over the last couple of seasons, but on the other hand, Keenum has experienced more success over the course of his career.

And Keenum is more familiar with the Shanahan-style offense, having played for Gary Kubiak in the past.

But Mills is number two on the depth chart, so he appears to be the starter should Stroud be ruled out for the game.

Which makes us wonder, should he be replaced by Keenum if he's not playing well against the Titans?

It's not like it would create a QB controversy as both Keenum and Mills are backups, and winning this game could greatly impact the team's playoff hopes.

Plus, DeAndre Hopkins is coming off a huge performance on Monday night, helping his team to upset the Dolphins. Will Texans corner Derek Stingley be able to keep D-Hop in check?

Be sure to watch the video above as we break it all down.
