Offensive tackles

Featured attraction: Oliver Ross, Steelers. With Walter Jones re-signed and Orlando Pace a virtual lock to return to the Rams, Ross is a less-than-thrilling top option at right tackle, but he is a solid perimeter run blocker.


Best range of roles: Jonas Jennings, Bills. He can play either tackle spot, and though he isn't ideally athletic, his ability to beat up smaller defenders with his 325-pound frame gives him fair value.


Best supporting blocker: Vaughn Parker, Redskins. Parker needs to get into a run-first scheme that won't ask him to constantly hold up against the league's best pass rushers.


Rising star: Kareem McKenzie, Jets. McKenzie has blossomed as a run blocker and is better off playing on the right side.
