Two weeks back, we outlined the major free-agent moves around the NFC West by taking a look at key departures and arrivals of the Seahawks' three divisional opponents - the Arizona Cardinals, San Francisco 49ers, and St. Louis Rams.

While those home-and-away contests will prove pivotal in determining which team walks away with the NFC West crown, the other 10 opponents on the Seahawks' schedule next season also deserve consideration as we move deeper into the NFL's open market.

Here's a look at how Seattle's 2015 opponents outside the NFC West have fared since free-agency opened on March 10:

HOME OPPONENTS

Carolina Panthers

Notable Departure: RB DeAngelo Williams. A mainstay in the Panthers' backfield the past nine seasons, Williams was released prior to the start of free agency and eventually signed a new deal with the Pittsburgh Steelers. Injuries littered Williams' 2014 regular season in Carolina and he played sparingly during the team's playoff run, recording just two carries for 14 yards in the Panthers' 31-17 divisional-round loss to the Seahawks.

Notable Addition: WR Ted Ginn. The wide receiver that excels as a return-man rejoins the same team he spent the 2013 season with after a one-year stay in Arizona with the Cardinals. Ginn brought back 26 punts for 277 yards and a touchdown and totaled 417 yards on 22 kickoffs last season. He played for the San Francisco 49ers from 2010-12, so he knows the Seahawks well, doing his most damage in a 2011 season-opening tilt at Candlestick Park when he returned a fourth-quarter kickoff (102 yards) and punt (55 yards) for touchdowns in less than a minute of game-time to give the Niners a 33-17 victory over the Seahawks in coach Jim Harbaugh's 49ers debut.

Chicago Bears

Notable Departure: DT Stephen Paea. The Bears will be without one of the League's top interior pass rushers this season with Paea joining the Washington Redskins in free agency. Paea, who spent his first four NFL seasons in Chicago, recorded a career-high 6.0 sacks and two forced fumbles last year.

Notable Addition: DE/LB Pernell McPhee. What the Bears lost in Paea's pass-rushing ability they made up for with the signing of McPhee, the former Baltimore Raven who had a career-high 7.5 sacks last season. McPhee was ranked No. 11 on NFL.com's list of 2015's Top 101 free agents.

Cleveland Browns

Notable Departure: TE Jordan Cameron. Concussion issues limited Cameron to 10 games last season, but he's still one of the more productive tight ends in the League who's just one year removed from an 80-catch, 917-yard, seven-touchdown campaign. Last year in Cleveland, Cameron caught 24 balls for 424 yards and two scores.

Notable Addition: WR Dwayne Bowe. The nine-year veteran wideout has said he hopes to return to the eye-popping numbers he posted in 2010, when he recorded 72 catches for 1,162 yards and 15 touchdowns as a member of the Kansas City Chiefs. This past year with the Chiefs was Bowe's first NFL season without a touchdown, but he still managed 60 catches for 754 yards - most among Kansas City's wide receivers.

Detroit Lions

Notable Departure: DT Ndamukong Suh. Seahawks fans may have wanted the dominant pass rusher in Seattle, but the Miami Dolphins were the ones who won over Suh's services. He had 8.5 sacks last season for the Lions, a team that also lost pass rusher Nick Fairley  to the Seahawks' NFC West rival St. Louis Rams.

Notable Addition: DT Tyrunn Walker. A good portion of Detroit's own free agents remain unsigned and the team hasn't been too active on the open market. Walker, a nose tackle who tallied 3.5 sacks over the past two seasons with the New Orleans Saints, will look to shore up a position group that lost so much with Suh and Fairley signing elsewhere this offseason.

Pittsburgh Steelers

Notable Departure: LB Jason Worilds. The Steelers' 27-year-old standout linebacker opted to retire this offseason to pursue other interests after just five years in the NFL. For Pittsburgh, Worilds had 15.5 sacks the past two seasons and entered the new League year at No. 10 on NFL.com's lisst of the Top 101 free agents.

Notable Addition: RB DeAngelo Williams. One of the Panthers' most-notable departures becomes one of the Steelers' most-notable additions. Williams saw limited action in 2014, but Pittsburgh still thinks the 31-year-old can produce. With the Panthers, Williams topped 700 yards rushing each year from 2011-13, but his last 1,000-yard season came in 2009.

AWAY OPPONENTS

Baltimore Ravens

Notable Departure: WR Torrey Smith. As referenced above, McPhee probably represents the Ravens' biggest loss on the defensive side of the football, but on the offensive side Smith is one worth noting. He's flashed plenty of big-play ability the past four seasons as one of quarterback Joe Flacco's favorite targets. Smith, who had a career-high 11 touchdowns last season, signed with the Seahawks' NFC West rival 49ers in free agency.

Notable Addition: FS Kendrick Lewis. A 16-game starter for the Houston Texans in 2014, Lewis should compete for a starting safety spot in 2015 as a member of the Ravens. He snagged two picks last year with the Texans and posted a career-high 84 tackles.

Cincinnati Bengals

Notable Departure: FS Taylor Mays. Ten of the Bengals' own free agents remain unsigned, so their departures list is still fairly thin. While Mays wasn't a starter in Cincinnati, he did prove to be a versatile backup who suited up for all 16 regular-season games. Mays signed on with the Minnesota Vikings in free agency.

Notable Addition: DE Michael Johnson. He returns to Cincinnati after one season with the Tampa Bay Buccaneers. The Bengals will hope Johnson can provide the same type of production he did in 2012, when he racked up a career-high 11.5 sacks. In his lone season with the Buccaneers, the 6-foot-7, 270-pound Johnson managed 27 tackles, 4.0 sacks, and two forced fumbles in 14 games played.

Dallas Cowboys

Notable Departure: RB DeMarco Murray. The Cowboys let the 2014 rushing champion (1,845 yards) walk away in free agency, with Murray inking a deal with the Philadelphia Eagles - a team that parted ways with running back LeSean McCoy in a trade with the Buffalo Bills. Murray was the Cowboys' offensive focal point and played an instrumental role in the team's 30-23 win over the Seahawks at CenturyLink Field this past October. In that game, Murray ran for 115 yards (4.0-yard average) and a touchdown against a stingy Seattle run defense that to that point had allowed a high of just 38 yards rushing to an individual on the season.

Notable Addition: DE Greg Hardy. He was the best pass rusher available in this year's crop of free agents, but he's also facing a possible suspension for violation of the NFL's personal conduct policy. He played in just one game for the Panthers last season before he was placed on the commissioner's exempt list, barring him from participating in any games or practices with Carolina. The season prior, however, Hardy racked up a career-high 15.0 sacks, a level of production the Cowboys hope he'll return to should he see the field.

Green Bay Packers

Notable Departure: CB Tramon Williams. He's the cornerback Seahawks wide receiver Jermaine Kearse beat for a 35-yard game-winning touchdown in January's NFC Championship at Seattle's CenturyLink Field, but looking back, Williams did have pretty good coverage on the play. Williams, a consistent starter for the Packers, signed with the Cleveland Browns in free agency.

Notable Addition: WR Randall Cobb. Technically, the wide receiver re-signed with his own club. But with Green Bay not acquiring any outside talent to this point, Cobb is the team's most notable signee to date. As a trusted target of quarterback Aaron Rodgers, Cobb made 91 catches for 1,287 yards, and 12 touchdowns a season ago - all career-highs in his fourth year as a pro.

Minnesota Vikings

Notable Departure: FB Jerome Felton. He's served as the lead-blocker for Vikings running back Adrian Peterson, who also might be on his way out of Minnesota. Felton now finds himself in Buffalo, operating in a Bills backfield that traded for the talents of former Eagles running back LeSean McCoy.

Notable Addition: QB Shaun Hill. The 14-year veteran quarterback returns to the same place he began his NFL career. Hill started roughly half of the Rams' games last season following the injury to then-starter Sam Bradford (who's since been traded to the Eagles), but will likely work in a backup/mentor role to Minnesota's Teddy Bridgewater, a 2014 first-round draft pick of the Vikings.
