On July 24, 2014, former Seahawks fullback and good friend Michael Robinson announced on NFL Network's Inside Training Camp, that Lynch would hold out of Training Camp while he waited for a restructured contract from the Seahawks.
Lynch and the Seahawks quickly agreed to new terms for the season, and Lynch served as the starting running back for the team, ahead of backups Robert Turbin and Christine Michael.

In the 2014 season opener, Lynch had 110 rushing yards and two rushing touchdowns in a 36–16 victory over the Green Bay Packers.
During Week 3 against the Denver Broncos, he completed the first overtime drive by rushing for a touchdown, giving the Seahawks a 26–20 victory over Denver in a Super Bowl rematch.
On November 2, against the Oakland Raiders, he had 67 rushing yards, two rushing touchdowns, and 76 receiving yards.
In the next game against the New York Giants, he had a stellar performance with 140 rushing yards and four rushing touchdowns in the 38–17 victory.
He scored 24 total points in the game, which was tied with Jonas Gray for the most by any player in a single game in the 2014 season.
He continued his successful string of games with 124 rushing yards against the Kansas City Chiefs in a loss the following week.

Lynch had a career-long 79-yard touchdown run against the Arizona Cardinals in Week 16, similar to his "Beast Quake" 67-yard scoring run in the 2011 Wild Card Round against the New Orleans Saints.
Four days later, Lynch was fined $11,050 by the NFL for his celebration of the score; falling back while extending the ball behind his head and grabbing his crotch.
The league considered his celebration an "obscene gesture" to constitute unsportsmanlike conduct.

The Seahawks finished with a 12–4 record and earned a first round bye.
He was named to the Pro Bowl for the fifth time in his career.
In the Divisional Round against the Carolina Panthers, he had 59 rushing yards in the 31–17 victory.
He contributed heavily to a late comeback in the NFC Championship against the Green Bay Packers in a rematch of the season-opener, catching a 26-yard pass to set up one touchdown and later scoring a touchdown of his own on a 24-yard run.
The Seahawks won 28–22 in overtime after trailing 19–7 with less than four minutes remaining in the game.
His 157 rushing yards in the game were a career postseason high for Lynch, as were his 183 total yards from scrimmage.

Lynch made headlines at Super Bowl XLIX Media Day on January 27, 2015, when he held a five-minute press conference, only answering "I'm just here so I won't get fined" to every question.
He has a history of unwillingness to talk to the media.

In Super Bowl XLIX, Lynch had 24 carries for 102 yards and a touchdown.
He also had a catch for 31 yards, but the Seahawks lost 28–24 to the New England Patriots as they failed to repeat as champions.
On Seattle's final offensive play of the game, they chose to pass the ball at the one-yard line instead of running it with Lynch, and Russell Wilson's pass was intercepted.
Lynch was visibly upset by the decision and left the Seahawks locker room without addressing the media.
He stated in a later interview with Conan O'Brien that he was "expecting the ball" prior to the play.
He was ranked ninth by his fellow players on the NFL Top 100 Players of 2015.
