A look at some memorable moments in Seahawks history that occurred on March 6:
2006: Shaun Alexander is re-signed to a multiyear contract, after being voted league MVP and leading the NFL in rushing (1,880 yards) and touchdowns (28) in 2005. Alexander would not have another 1,000-yard rushing season before being released during the 2007 offseason, but he remains the franchise career leader in rushing yards (9,429), touchdowns (122) and rushing attempts (2,176).
1975: John Thompson is named the team's first general manager. Thompson had been executive director of the NFL Management Council.
1997: Bennie Blades, a Pro Bowl safety from the Lions, signs with the Seahawks – joining his younger brother, Brian, who would rank No. 2 on the team's all-time reception list by the time he retired after the 1998 season. Bennie played in 10 games in '97 before an injury forced him to retire.
1998: Brian Habib, a guard on the Broncos' Super Bowl championship team, agrees to sign with the Seahawks in free agency. Habib, who played at the University of Washington, started all 32 games in two seasons with the Seahawks.
On October 5, 2010, the Seahawks acquired Marshawn Lynch and in his nine years in the NFL Lynch has made some truly spectacular plays, rightfully earning the nickname Beast Mode.
2015: Marshawn Lynch, who is coming off his fourth consecutive 1,000-yard rushing season, signs a two-year contract extension.
