Best trade No. 2 - Marshawn Lynch (2010)
The Seahawks traded a 2011 fourth-round pick and a 2012 fifth-round pick to the Buffalo Bills for Marshawn Lynch.
This is a no-brainer, right? I'll get what the Bills ended up getting out of the way first. With the draft choices that Buffalo got they chose Chris Hairston in 2011 and Tank Carder in 2012. Carder never played for the Bills but he did play five years with the Browns. Left tackle Hairston played three years with the Bills and was out of the league after six seasons.
Meanwhile, Lynch greatly helped change the culture in Seattle. He added a ferocious mentality to an offense that wasn't at all scary before Lynch arrived. In his first season in Seattle, he didn't have a 100-yard game in the regular season but he had three games with 75-yards-plus. That changed in the playoffs, however, when Lynch ran for 131 yards against the New Orleans Saints in Seattle's shocking Wild Card victory. That was the game, of course, that featured Beast Mode 1.0.
Lynch played parts of seven years with Seattle, won a Super Bowl, and should have been part of a second Super Bowl team. Twice he led the league in rushing touchdowns (2013 and 2014) and had four years with at least 1,204 yards rushing. He was a Pro Bowler from 2011 through 2014 and was a first-team All-Pro in 2012.
Lynch is fourth all-time in Seahawks history in rushing yards (6,381), second in touchdown runs (55), and second in rushing yards-per-game (76.9).
