The Indianapolis Colts were able to pull one out in Week 13 against the Houston Texans, largely due to the Texans inability to secure a snap in scoring range, rather than the Colts ability to close out the game. The Colts led at halftime 24-20, and managed to only score via a safety throughout the remainder of the game.
That sort of lopsided play between halves, simply will not cut it in the final stretch of the season where the team has the Las Vegas Raiders and Pittsburgh Steelers among their final four games of the year.
