The Colts were a middling 18th (out of 32) in ESPN’s initial NFL Power Rankings, which were recently released.
Here is the Colts' brief write-up:
The Colts came in third in the AFC South, behind the Titans (12th), Texans (14th), and the Jaguars were 28th (that seemed low to me). The top-five was rather obvious: Power Rankings top five: Patriots, Falcons, Seahawks, Steelers, and Packers.
