If Hou loses 2 and the Ravens win both, Pit loses both and at least 1 of Ten and Ind finish 10-6 then it will come down to SoV with the Ravens holding a half game lead with results as they now stand. Unfortunately, the remaining games influencing the SoV tiebreaker strongly favor the Texans who have beaten more contenders.
The biggest game remaining on the schedule for an SoV tiebreaker against either the Texans or Colts is the Tampa Bay/Dallas game. The Ravens need TB to beat Dallas in week 16 on the road in the only double-count game (Ravens pick up a SoV win while both Colts and Texans miss an opportuntity to do so) on the remainder of the schedule. That's not the only game influencing SoV, but it's the most important. It would not feel good to have the Ravens fortunes in the hands of an unmotivated TB team playing out the string on the road.
