The best ability is availability. Unfortunately, the Colts don’t have many players who have been available for all of their games. It has hurt their ability to win games that they should win, such as their game against Pittsburgh or home against the Dolphins.
Houston will come in Thursday as the healthier team. They will have more playmakers available for the big game. They aren’t missing any big time receivers or their quarterback. But they are missing the psychological advantage, because the Colts own that.
Indy owns that because they have owned the Texans recently. The won two out of three last year, including in the playoffs in Houston, and won the previous matchup this season.
