The Seattle Seahawks and Pete Carroll are negotiating a contract extension.

Carroll is entering the final season of a three-year deal he signed after the Seahawks won the Super Bowl.

Carroll is 64 and has reinvented himself as one of the NFL's most philosophically open and psychologically agile coaches.

There has been speculation that Carroll could retire after the 2016 season with Tom Cable in line to replace him.

The Seattle Seahawks are not expected to attempt to recoup the $5 million signing bonus given to Marshawn Lynch.

Lynch has decided to retire this offseason and both sides appear pleased with the outcome.

Lynch announced his retirement at the age of 29 during the Super Bowl.

Tarvaris Jackson plans on testing free agency.

Jackson signed a one-year, $1.5 million deal last offseason to remain the backup of the Seattle Seahawks.

Jackson signed last year's deal in June.

The agent for Marshawn Lynch confirmed he will retire from the NFL at the age of 29.

Lynch posted a photo during the Super Bowl of his cleats hanging up with a peace-sign emoji.

Lynch was a first round pick by the Buffalo Bills in 2007 and became one of the league's best running backs when joining the Seattle Seahawks in 2010.

Thomas Rawls will likely become Lynch's replacement at running back for the Seahawks.

The New England Patriots are the favorites to win the 2016 Super Bowl at 9-1.

The Patriots lost to the Denver Broncos in the AFC Championship Game, while the team with the second best odds, the Carolina Panthers, lost to the Broncos in the Super Bowl.

The Broncos have the ninth best odds at 18-1.

Marshawn Lynch has been telling those close to him he plans on retiring from the NFL this offseason.

Some of his teammates are attempting to convince Lynch to change his mind.

Lynch turns 30 in April and was limited to just 111 carries and 417 yards in the regular season due to a hamstring injury.

Lynch didn't play in the Seattle Seahawks' Wild Card win over the Minnesota Vikings and he rushed for 20 yards on six carries in the Divisional Round against the Carolina Panthers.

In January, Seahawks general manager John Schneider revealed that Lynch was "leaning toward" retirement, and those feelings have only strengthened.
