AFC North. 2014: 11-5. Pittsburgh Steelers. 7. player. 55. <p>The Steelers just may enter 2015 with the most explosive offense in the league. It sure looked that way after Ben Roethlisberger tossed a pair of touchdowns to Martavis Bryant and Markus Wheaton in the first half against the Jaguars.</p> <p>After a shortened rookie year, Ryan Shazier is looking really, really good. He was all over the field on Friday, leading the team with six tackles. He’s the poster boy of what the Steelers’ defense is becoming: a fast, young unit. In the blink of an eye, the Steelers shepherded out their aging veterans on defense and replaced them with guys like Shazier.</p>

Next: 6. Indianapolis Colts
