The Colts, with their playoff chances dwindling, are massive underdogs against the Cowboys Sunday night at AT&T Stadium.
Indianapolis lost to the Steelers, 24-17, at home on Monday and are back on prime-time this week in a must-win situation. Dallas took care of the Giants, 28-20, on Thanksgiving to improve to 5-1 at home.
With a few extra days of rest, the Cowboys were installed as 12.5-point favorites. The line is the largest of the season for either team. Dallas did not cover its only other double-digit spread of the season, which was 10 points last week against New York.
