The AFC North is running a series where every position will be ranked and what could change at that position.
1. STEELERS: Pittsburgh had the top-ranked pass defense, and it wasn't all about the pass rush this time. Actually, the pass rush was extremely inconsistent this season, so that No. 1 ranking is more of a reflection of the Steelers' secondary. Cornerback Ike Taylor and free safety Ryan Clark had career years. Taylor's season, though, was marred by a late-season decline that ended with him getting stiffed-armed by the Broncos' Demaryius Thomas on the touchdown that ended the Steelers' season. Clark had the best season of any safety in the division, which is saying a lot when Troy Polamalu and Ed Reed are in the AFC North. He finished second in the division with 100 tackles. Polamalu was solid, but didn't play up to his usual spectacular level. William Gay was a pleasant surprise, taking back the starting cornerback job that he lost in 2010. What could change: Gay is an unrestricted free agent, but it shouldn't take much to retain him. Look for rookie cornerbacks Cortez Allen and Curtis Brown to make more of an impact in their second seasons.
2. RAVENS: This group exceeded expectations, and did so in a surprising manner. Instead of starting Domonique Foxworth and Chris Carr at cornerback, the Ravens finished fourth in pass defense with Lardarius Webb and Cary Williams. Webb was the division's top cornerback, recording five interceptions and breaking up 20 passes (and that doesn't include three interceptions in the playoffs). Williams was a physical presence at corner. The biggest disappointment was Reed, who intercepted three passes -- his fewest in a season where he played more than 12 games. The Ravens' other safety, hard-hitting Bernard Pollard, provided more of an impact than Reed. First-round pick Jimmy Smith endured an up-and-down rookie season. What could change: Smith should take over for Williams as a starting cornerback this season. Foxworth is expected to get cut, and the same could happen to Carr. Both backup safeties, Tom Zbikowski and Haruki Nakamura, are free agents, but I suspect Nakamura will get re-signed.
3. BROWNS: Joe Haden showed signs of being a shutdown corner, even though he failed to make an interception. He held his own against some of the best receivers in the NFL, from Larry Fitzgerald to Brandon Marshall. His worst games came against Bengals wide receiver A.J. Green. While Haden is among the division's best cornerbacks, Sheldon Brown was the worst starting corner in the AFC North. Brown's biggest asset is the experience he provides to a young secondary. The defensive backfield was hurt by the loss of strong safety T.J. Ward, who missed the final 10 games with a foot injury. Teams took advantage of Ward's replacement, Usama Young. Free safety Mike Adams beat out Young for a starting job in training camp. Dimitri Patterson was a reliable nickelback, breaking up a dozen passes. What could change: The Browns might replace Adams, who is a free agent, and they could give rookie seventh-round pick Eric Hagg a shot at doing so. Cleveland is very interested in bringing Patterson back. It wouldn't be a surprise if Patterson starts in place of Brown.
4. BENGALS: Leon Hall is perhaps the most valuable cornerback in the division. In the first nine games with Hall, the Bengals gave up eight touchdown passes. In the last seven regular-season games without him (he had a season-ending Achilles injury), they allowed 12 touchdown passes. The Bengals replaced Hall with Adam Jones, who was extremely erratic in coverage. The Bengals value the veteran leadership of Nate Clements, but the cornerback is looking past his prime. Only nickelback Kelly Jennings struggled on a more consistent basis. Safety Reggie Nelson allowed some big plays early, but he was stingy in pass defense late in the season. The other safety, Chris Crocker, had trouble covering the more athletic tight ends in the league. What could change: The Bengals need to draft a cornerback in the first round to press Clements for a starting role and become his eventual replacement. Nelson is a free agent, but he is considered a priority to get re-signed. The Bengals are expected to part ways with Jones, who is a free agent.
