Teams have added 254 players in the draft since ESPN's NFL Power Rankings last appeared six weeks ago. We've seen Carson Palmer join the Arizona Cardinals and Darrelle Revis join the Tampa Bay Buccaneers, among other changes involving veteran players.

Our voters mostly shrugged when asked to update their ballots.

No team moved more than three spots higher (Cardinals) or three spots lower (Cleveland Browns) in the rankings when John Clayton, Dan Graziano, Jamison Hensley and Ashley Fox joined me in casting ballots.

Teams made larger moves up and down individual ballots.

Clayton and I moved up the Cardinals at least seven spots to reflect the change from Ryan Lindley and John Skelton to Palmer, plus continued improvements to the offensive line. The Dallas Cowboys and New York Jets fell several spots on some ballots.

Overall, however, there wasn't a great deal of movement. We did have our disagreements. None stood out more to me than a couple involving Graziano, our blogging brother from the NFC East. He had the Saints significantly lower and the Vikings significantly higher than our other voters ranked those teams.

Dan isn't exactly buying playoff tickets in New Orleans simply because Sean Payton is returning to the Saints' sideline.

"The Saints gave up the most yards in league history in 2012," he explained. "I just think it's a much longer way back for that defense than people give it credit for. Not sure how Payton's return turns them from one of the worst defenses in the history of the sport into a playoff-caliber one in one offseason."

Fair enough. But what about that No. 8 ranking for the Christian Ponder-led Vikings? Everyone else ranked them 17th.

"I don't understand the rush to drop a 2012 playoff team that replaced Percy Harvin with Greg Jennings and just crushed the draft," Graziano said. "Why won't they be good again?"

Harvin would be the more dynamic receiver of the two, in my view. The Vikings arguably gave up too much for the 29th pick in the draft, acquired from New England. And it's debatable, at least in my mind, whether Adrian Peterson can carry the team every week the way he did down the stretch last season.

All things to discuss as the offseason continues. First, we take a closer look at the rankings with May fast approaching:

Falling (10): Cleveland Browns (-3), Buffalo Bills (-2), Chicago Bears (-2), Dallas Cowboys (-2), Detroit Lions (-2), New Orleans Saints (-2), Carolina Panthers (-1), Indianapolis Colts (-1), New England Patriots (-1), New York Jets (-1).

Rising (11): Arizona Cardinals (+3), Kansas City Chiefs (+2), New York Giants (+2), Tampa Bay Bucs (+2), Washington Redskins (+2), Cincinnati Bengals (+1), Green Bay Packers (+1), Jacksonville Jaguars (+1), Miami Dolphins (+1), Oakland Raiders (+1), Philadelphia Eagles (+1).

Unchanged (11): Atlanta Falcons, Baltimore Ravens, Denver Broncos, Houston Texans, Minnesota Vikings, Pittsburgh Steelers, San Diego Chargers, San Francisco 49ers, Seattle Seahawks, St. Louis Rams, Tennessee Titans.

Deadlocked: We broke one tie. The Bears prevailed over the Saints at No. 13 based on previous ranking.

Like minds: One spot separated the highest and lowest votes for the Texans. Two votes separated highest and lowest votes for the Seahawks, 49ers, Packers, Patriots, Titans, Browns and Jets.

Agree to disagree: Ten spots separated highest and lowest votes for the Saints, the largest gap for any team. At least seven spots separated highest and lowest votes for five other teams. A look at the teams generating the largest high-low disparities:

Saints (10): Fox ranked the Saints 10th, higher than any other voter ranked them. Graziano ranked them 20th, lower than any other voter ranked them.

Cardinals (9): Sando and Clayton 20th, Fox 29th.

Vikings (9): Graziano eighth, every other voter 17th.

Steelers (8): Clayton 10th, Fox 18th.

Panthers (7): Hensley 18th, Clayton 25th.

Cowboys 7: Graziano 17th, Hensley 24th.

Power Rankings histories: These colorful layered graphs show where each NFL team has ranked every week since the 2002 season.

Ranking the divisions: The NFC West remained the highest-ranked division with an 11.0 average ranking for its teams, up from 12.3 last time. Teams from the NFC North were second at 14.2, followed by the NFC South (14.6), AFC North (15.3), NFC East (17.8), AFC South (18.7), AFC West (19.4) and AFC East (21.3).
