ESPN put together a full list of the top rosters in the NFL (Insider), based on Pro Football Focus grading. Not surprisingly, the Seahawks came out on top.
PFF names Richard Sherman, Earl Thomas, Marshawn Lynch, Jimmy Graham, and Russell Wilson as Seattle's top players. They name Lemuel Jeanpierre, Justin Britt, J.R. Sweezy, and Tony McDaniel as players that could be upgraded in 2015.
Per their explanation:
The offensive line remains below average at best, but Wilson, Lynch and now Graham give the Seahawks weapons perfectly suited to make up for any blocking issues, especially when their read-option plays are added into the equation. Lynch broke 130 total tackles last season, including the playoffs, while no other back got near 100.
The Legion of Boom was very banged up by the end of that Super Bowl, but Sherman and Thomas remain elite talents, and there are quality players all over the defense. Even free-agent pickup Cary Williams, much maligned in Philadelphia, could have a pretty good year in a defense that puts better talent around him and supports his aggressive play. With the roster in this kind of shape, the Seahawks aren't going anywhere for a while.
The Packers come in second, followed by the Ravens, Patriots, and Broncos. A few surprises may be: the Vikings at #8, the Steelers at #12, and the Falcons at #31. The Niners came in at #17, and the Rams (#22) were surprisingly ranked above the Cardinals (#24).
