The NFC's representative in each of the past three Super Bowls have hailed from the West.

If this thorny pack of teams makes it a fourth year in a row, the Browns will have a shot to say they beat the NFC champion during the regular season.

Here's how their rosters are looking a few months after the West-winning Seahawks came up a few yards short in Super Bowl XLIX.

49ers

New faces: DT Darnell Dockett, OL Erik Pears, WR Torrey Smith, DB Shareece Wright

Coming back: DB Chris Cook, QB Blaine Gabbert

Biggest loss: LB Patrick Willis (retired)

Other losses: LB Chris Borland (retired), DB Perrish Cox (Titans), DB Chris Culliver (Redskins), RB Frank Gore (Colts), OL MIke Iupati (Cardinals), WR Stevie Johnson (Chargers), DL Ray McDonald (Bears), LB Dan Skuta (Jaguars)

Notables on the market: WR Michael Crabtree, WR Brandon Lloyd, QB Josh Johnson

The big storyline: The losses in free agency would be enough to think it could be a rebuilding year for the 49ers. The surprise retirements of the top two middle linebackers made it even tougher on first-year coach Jim Tomsula, who takes over a franchise with a solid quarterback but lots of holes to fill on both sides of the ball. Just a few years removed from representing the West in the Super Bowl, the 49ers are poised to be projected as missing the playoffs for a second straight season.

Cardinals

New faces: OL Mike Iupati, DL Corey Peters, DL Cory Redding, C A.Q. Shipley, LB Sean Weatherspoon, DL LaMarr Woodley

Coming back: LS Mike Leach

Biggest loss: DL Dan Williams (Raiders)

Other losses: DB Antonio Cromartie (Jets), DL Darnell Dockett (49ers), OL Paul Fanaika (Chiefs), WR Ted Ginn (Panthers)

Notables on the market: LB John Abraham, TE Rob Housler, DL Tommy Kelly, QB Ryan Lindley

The big storyline: There's no questioning the Cardinals' defense, which was one of the league's best in 2014 and served as the backbone through the team's playoff run. The questions linger most at quarterback, where the Cardinals lost multiple starters to injury last season, and running back. The Cardinals didn't move on the position in free agency, but have been linked to Minnesota's Adrian Peterson and have been tabbed by most as a team likely to select one of the draft's top players at the position. Whoever is carrying the ball for Arizona will run behind a stout offensive line that has been solidified by the additions of Iupati and Shipley.

Rams

New faces: LB Akeem Ayers, DL Nick Fairley, QB Nick Foles

Coming back: WR Kenny Britt, TE Lance Kendricks

Biggest loss: DL Kendall Langford (Colts)

Other losses: QB Shaun Hill (Vikings), QB Sam Bradford (Eagles), OL Mike Person (Falcons)

Notables on the market: OL Joe Barksdale, DL Alex Carrington, OL Jake Long

The big storyline: The Rams made all their noise at the start of free agency with a trade when they sent Bradford to the Eagles for Foles and some better draft picks. While you could debate all day about who's the better quarterback, the Rams get a fresh start with a quarterback who, perhaps, doesn't have as high of a ceiling as Bradford, but has fewer injury issues and a more recent track record of success. St. Louis didn't have as much room to work with under the cap as most teams, but it was able to add even more beef to its defensive line with the addition of Fairley, who was signed to a one-year "prove it" contract.

Seahawks

New faces: TE Jimmy Graham, DB Will Blackmon, DL Ahtyba Rubin, DB Cary Williams

Coming back: TE Anthony McCoy, LB Mike Morgan

Biggest loss: C Max Unger (traded to Saints)

Other losses: OL James Carpenter (Jets), S Jeron Johnson (Redskins), DB Byron Maxwell (Eagles), DL O'Brien Schofield (Falcons), LB Malcolm Smith (Raiders)

Notables on the market: QB Tarvaris Jackson, TE Zach Miller

The big storyline: The Seahawks' Super Bowl run wouldn't have happened without some shrewd drafting from John Schneider and Pete Carroll, but they found a way to shake things up with a trade that rocked the NFL. Seattle's end of the deal made all the headlines, as it gave Russell Wilson one of the game's premier playmakers with the addition of Graham, but the Seahawks paid a steep price when they parted with this year's first-round pick and Pro Bowl center Max Unger. With Carpenter leaving for the Jets, the Seahawks will have to move forward without two pieces from last year's starting offensive line. Much like the Browns, the Seahawks quickly moved to fill a hole in the secondary after a starting cornerback was lost, essentially trading Maxwell to the Eagles for Williams.
