AFC East

. New England Patriots: C

The Patriots lost four cornerbacks off their Super Bowl-winning squad and will have work to do to make up for Tom Brady's season-opening suspension.

. Buffalo Bills: B–

Rex Ryan has pledged to infuse his one-of-a-kind style on the playoff-starved Bills, but how far can a team go without a quarterback?

. Miami Dolphins: B

Miami landed free agency's biggest fish, but Ndamukong Suh won't be a cure-all for the Dolphins as they try to pass the Patriots.

. New York Jets: A–

The Jets sent their rebuild into hyperdrive with a staff overhaul and the return of Revis Island.

AFC North

. Baltimore Ravens: B+

Several key names (Smith, Ngata, McPhee) are gone, but the Ravens have reloaded seamlessly too many times to fly under the radar anymore.

. Cincinnati Bengals: B–

The Bengals appear content with their roster ahead of a pivotal year for the coaching staff and franchise quarterback Andy Dalton. Is that a good thing?

. Cleveland Browns: B–

The Browns had a lot to fix heading into the off-season, and they made an overhaul of their porous defensive line the top priority.

. Pittsburgh Steelers: C

The Steelers are putting a lot of pressure on their draft picks to fill the holes on a defense that got lit up in 2014.

AFC South

. Houston Texans: B+

From the league's worst record to playoff contention in 12 months, the Texans made moves with designs on threatening for a division title and beyond.

. Indianapolis Colts: B+

Stocked with veteran offensive weapons and new faces on defense, the Colts expect their Super Bowl chase to be taken seriously.

. Jacksonville Jaguars: A–

With another strong off-season under their belt, it's time for the Jaguars to start climbing up the standings.

. Tennessee Titans: C

After drafting Marcus Mariota with the No. 2 pick, Titans remain unsure of how smoothly he'll develop in NFL.

AFC West

. Denver Broncos: C+

Denver's new coaching staff is tasked with avoiding last year's late-season fade and keeping Peyton Manning's Super Bowl window open.

. Kansas City Chiefs: B–

To turn around a stagnant offense, the Chiefs can't have their receivers be shut out of the end zone for a second straight year.

. Oakland Raiders: A–

First-round pick Amari Cooper is just the latest addition to a young core that brings the Raiders to the precipice of a return to relevancy.

. San Diego Chargers: B–

With Melvin Gordon in the fold, it's all smiles in San Diego. But what will the O-line blocking for him look like?

NFC East

. Dallas Cowboys: B+

Will Dez Bryant sign? Will La'el Collins start? Amid a hectic off-season, plenty of questions remain in Dallas.

. New York Giants: B–

If the Giants' draft picks stumble early and the defense can't turn itself around, Tom Coughlin and his staff could be out the door.

. Philadelphia Eagles: B

New QB, new running backs, new top receiver ... Chip Kelly's aggressive shuffling of the offense will make or break the Eagles' hopes.

. Washington Redskins: B+

New GM Scot McCloughan brought some logic and restraint to Washington's off-season signings, but they won't mean much without an RGIII revival.

NFC North

. Chicago Bears: B+

This off-season brought a complete overhaul to the Bears' front offices, but can they solve the Jay Cutler puzzle?

. Detroit Lions: B+

Thanks to a stable secondary and offense, the Lions should remain contenders in tough NFC North.

. Green Bay Packers: B

The Packers approached the off-season with their typical passive manner, but consider it a win that they re-signed Randall Cobb and Bryan Bulaga.

. Minnesota Vikings: B

After proving himself as a head coach in 2014, Mike Zimmer is ready to push the Vikings even further in 2015.

NFC South

. Atlanta Falcons: B

On paper, the Falcons made constructive changes this spring, especially in the draft. Will the product on the field make real progress?

. Carolina Panthers: C+

The Panthers made Cam Newton the NFL's latest $100 million quarterback but left his supporting cast with some unsettling holes.

. New Orleans Saints: B

General manager Mickey Loomis has made dramatic changes to his roster in consecutive off-seasons. Will fresh blood send the Saints back to the playoffs?

. Tampa Bay Buccaneers: B

All eyes will be on Jameis Winston to turn around the Bucs' fortunes after a snakebitten 2014 campaign.

NFC West

. Arizona Cardinals: B+

The Cardinals hope they've addressed last season's late fade with a few shrewd moves, but replicating the results of former defensive coordinator Todd Bowles will be a tall task.

. San Francisco 49ers: D

After a tumultuous off-season packed with turnover, both at the player level and the coaching level, where do the 49ers go from here?

. Seattle Seahawks: A-

Championship windows can close quickly for NFL teams, but Seahawks coach Pete Carroll knows that the window is still open for this Seattle team.

. St. Louis Rams: B-

Known for his defensive mindset, Rams coach Jeff Fisher showed a renewed commitment to his offense this off-season by trading for Nick Foles and drafting Todd Gurley. But will that be enough to create a winning team?
