When Seahawks coach Pete Carroll was asked earlier this month about the idea of adding size at receiver, he noted that the Seahawks top receivers are quicker, smaller players, and said, "we're always looking."
On Tuesday, the Seahawks added a big receiver with an impressive résumé, signing six-time Pro-Bowler Brandon Marshall, who at 6-foot-5, 232 pounds, gives the Seahawks a big-bodied pass catcher with a long history of success.
To make room on the 90-man roster, the Seahawks waived fullback Marcus Martin, who was signed as an undrafted rookie free agent out of Slippery Rock earlier this month.
Marshall, 34, has eight 1,000-yard seasons in his 12-year NFL career, and has finished with double-digit touchdown totals four times, including in 2015 when he matched Doug Baldwin for the NFL lead with 14.
Marshall began his career with the Denver Broncos as a fourth-round pick out of UCF in 2006, and also played for the Dolphins, Bears, Jets and most recently the Giants, though his 2017 season ended after just five games because of an ankle injury. Prior to last season, Marshall had proven very durable, playing at least 13 games in every season of his career, and only missing four games between 2011 and 2016.
Seahawks fans likely remember Marshall from his 2016 game against Seattle when he had 4 catches for 89 yards and a touchdown in an entertaining battle with Richard Sherman, who ended up with two interceptions in a Seahawks victory over the Jets.
"I knew coming into this game that it'd be a dog fight with Brandon," Sherman said after that game. "He's going to end up in the Hall of Fame with a gold jacket because he's done it everywhere he's been. He did it in Miami, he's doing it in New York, he did it in Denver. He's just a great player and he's going to make his plays and I knew that coming in. That's how the matchups go."

Marshall also had a memorable game in a 2012 Seahawks victory over the Bears, a game that was something of a coming out party for Russell Wilson. Then a rookie, Wilson led a touchdown drive late in the fourth quarter to give Seattle a lead, but Seattle and Wilson needed another touchdown in overtime for the victory because Marshall helped the Bears force overtime with a 56-yard catch that set up a tying field goal late in regulation.
In addition to his impressive play on the field, Marshall has impressed Carroll off the field, most notably when in 2017 he spoke to owners and executives at the annual league meetings.
"He had an extraordinary impact in his presentation," Carroll said last spring. "I thought he was spot on. And he's just one of the many guys that have so much to offer our league and offer the culture and all. He spoke from a place that I thought was really a great opportunity for our owners to hear from. He's the first player to ever speak in an NFL meeting, and he made a great opening statement to what the other players have to offer. In particular, I really believe that the players are at the core of what our game is all about, and they always have been."
Marshall, who in 2011 was diagnosed with borderline personality disorder, co-founded PROJECT 375, a non-profit that is dedicated to the education, support and treatment of mental health. Since its founding, PROJECT 375 has raised more than $1.6 million while also bringing awareness to mental health issues.
