The Seattle Seahawks have signed Tyler Lockett to a three-year, $31.8 million contract extension.

The deal has a maximum value of $37.8 million and $20 million guaranteed.

The 25-year-old Lockett was entering the final year of his rookie contract. 

Lockett suffered a compound fracture of his leg in a Christmas Eve game against the Arizona Cardinals.

Lockett made it back by the start of last season but estimated recently that he was playing at about 75-80 percent while coming off the injury.

The Seattle Seahawks have gone through as much roster upheaval as any still competitive team in recent memory.

Pete Carroll compares the experience to his time at USC.

“This feels like when you’re in college,” Carroll said. “That senior class graduated—those guys that did all the playing for you. But that doesn’t mean that you can’t have a good team next time around. New players, new coaches. There’s new juice about everything that we’re doing. I go back and do all my teaching again. I’m really happy about it.”

“I mean, this is what the league is now," said John Schneider. "We move guys all the time. For a while, we were able to reward guys here at the top of their positions. Then we had to make decisions—who to keep and who not to keep—and we got the bad injury news on Cliff Avril and Kam Chancellor [forced to retire due to injuries]. We didn’t see those coming.

“But there’s another thing. You know Pete. He preaches competition, open competition, every single day. It’s hard to preach that when you got the best corner and the best free safety and the best strong safety and the best middle linebacker, all young, and you know those guys are locked in there. They were the youngest team to win it all. You don’t tear that apart.

“Now, this. It’s fun. Lots of enthusiasm. So much spirit, so much new. It’s pretty cool.”

Beyond strictly looking at wins and losses, DVOA by Football Outsiders gives a clear picture of team performance.

The following Infographic shows the past 10 years of DVOA rankings (2008-2017) for the Seattle Seahawks.

Finishing first in DVOA over the first four seasons of Russell Wilson's career was an extraordinary run for the Seahawks. In hindsight, winning only one Super Bowl could be considered a missed opportunity for Seattle. The Seahawks could drop even further in 2018 as they remake their roster.

Ten-Year DVOA Rankings: Arizona Cardinals, Atlanta Falcons, Baltimore Ravens, Buffalo Bills, Carolina Panthers, Chicago Bears, Cincinnati Bengals, Cleveland Browns, Dallas Cowboys, Denver Broncos, Detroit Lions, Green Bay Packers, Houston Texans, Indianapolis Colts, Jacksonville Jaguars, Kansas City Chiefs, Los Angeles Chargers, Los Angeles Rams, Miami Dolphins, Minnesota Vikings, New England Patriots, New Orleans Saints, New York Giants, New York Jets, Oakland Raiders, Philadelphia Eagles, Pittsburgh Steelers, San Francisco 49ers, Tampa Bay Buccaneers, Tennessee Titans, Washington Redskins

Seattle Seahawks running back J.D. McKissic is expected to be sidelined four to six weeks because of a broken bone in his foot, according to a source.

McKissic suffered a Jones fracture, which is on the outside of his foot.

He was competing with Mike Davis and C.J. Prosise for a roster spot behind Chris Carson and Rashaad Penny on the depth chart.

Chris Carson is leading Rashaad Penny for the starting running back job with the Seattle Seahawks.

Pete Carroll said everything Carson has done this offseason "has just been top drawer."

Penny was the 27th overall pick in the 2018 NFL Draft. Penny suffered a broken finger that required surgery.

Penny is expected to be back by Week 1, according to Carroll, and he figures to still have a sizable role in Seattle's offense as a rookie. 

The Buffalo Bills have agreed to sign Jon Ryan.

Ryan was released by the Seattle Seahawks on Monday as Michael Dickson was set to be their punter.

Ryan will compete for the punter job with Colton Schmidt.

The Seattle Seahawks have terminated the contract of Marcus Smith in what was a surprise move.

Pete Carroll said "some personal reasons" factored into Smith's release. He said earlier in the week that Smith's absence from practice was due to a family issue.

Carroll said Smith's health wasn't an issue. Asked if Smith had requested his release or if it was a mutual decision or the team's choice, Carroll paused and said: "We talked through the whole thing. I just kind of want to leave it alone because it's personal stuff and I'd just like to leave it there."

Smith recorded 2.5 sacks in a rotational role for the Seahawks last season after the Philadelphia Eagles, who had drafted Smith in the first round in 2014, waived him before training camp.

Seattle Seahawks rookie Rashaad Penny will undergo surgery Wednesday morning to repair a broken bone in his finger, according to a source.

The surgery is expected to sideline Penny for three to four weeks, which would put his status for Week 1 in question.

Prior to the injury, Penny was battling Chris Carson to be Seattle's top running back.
