The Indianapolis Colts are on a roll, having won 10 of their last 11 games, including last week's wild-card victory over the Houston Texans.
The Colts displayed three of the weapons needed to have success in the postseason in that 21-7 road win. Their offensive line gave quarterback Andrew Luck brilliant protection, and it opened holes for Marlon Mack in the running game.
The defense also kept the favored Texans from establishing any traction. That may have been the most impressive factor, since Houston had quarterback Deshaun Watson and wide receiver DeAndre Hopkins. That duo was as dangerous as any in the NFL.
