A look at a memorable moment in Seahawks history that occurred on April 18:

1998: Linebacker Anthony Simmons is selected in the first round of the draft. Simmons would lead the Seahawks in tackles three times – including 147 in 2000, which ranks as the third-highest single-season total in franchise history behind Terry Beeson (153 in 1978) and Chad Brown (150 in 1998).

A look at some memorable moments in Seahawks history that occurred on March 4:

2003: The club re-signs unrestricted free agents Anthony Simmons and Antonio Cochran. Simmons then leads the Seahawks in tackles for the third time in four seasons.

2004: Grant Wistrom signs with the Seahawks in free agency. The former Rams defensive end starts 41 games over the next three seasons and is selected as captain on the Seahawks’ 2005 Super Bowl team.

2012: Marshawn Lynch, on the verge of becoming an unrestricted free agent, re-signs with the Seahawks. The Beast Mode back then puts together an All-Pro and Pro Bowl season while posting career-bests in rushing yards (1,590), per-carry average (5.0), longest run (77 yards) and 100-yard rushing games (10).

1984: Dan Doornink carries the ball 29 times for 126 yards as the Seahawks rush for 205 yards in handing the defending Super Bowl champion Raiders a 13-7 loss in a wild-card playoff game at the Kingdome. Dave Krieg, who completes only 4 of 10 passes, throws 26 yards to Daryl Turner for the Seahawks’ only touchdown. The defense shuts out the Raiders until midway through the fourth quarter as it sacks Jim Plunkett six times, including 2.5 by Jacob Green, and intercepts him twice.

1991: The Seahawks win their final game under coach Chuck Knox, 29-9, over the Rams in the season finale at the Kingdome as James Jones runs for two touchdowns. Knox would return to the Rams as their coach in 1992.

1996: Michael McCrary registers four sacks, Lamar Smith runs for two touchdowns and Joey Galloway catches a 32-yard TD pass from Gino Torretta as the Seahawks rally for a 28-21 victory over the Raiders in Oakland. The sack barrage in the season finale allows McCray to finish with an AFC-leading 13½.

2002: Shaun Alexander runs for two touchdowns, Matt Hasselbeck passes for 303 yards, Rian Lindell kicks three field goals, Reggie Tongue intercepts two passes and Anthony Simmons has 11 tackles and an interception in a 30-10 victory over the Rams in Seattle.

Sherman Smith

1976: The expansion Seahawks capture their first regular-season victory at home with a 30-13 win over the Atlanta Falcons at the Kingdome as Sherman Smith becomes the first Seahawk to post a 100-yard rushing performance (124 yards on 14 carries).

1999: Jon Kitna passes for three touchdowns, Ricky Watters scores twice as part of a 133-yard rushing effort and defensive tackle Cortez Kennedy intercepts a pass in a 37-20 victory over the Cincinnati Bengals at the Kingdome.

2004: Shaun Alexander rushes for 160 yards and two touchdowns; Matt Hasselbeck passes for three TDs, including two to Darrell Jackson, who has five catches for 114 yards; and linebacker Anthony Simmons returns an interception for a score in a 42-27 victory over the 49ers in San Francisco.

1986 – The Seahawks win their opener 30-0 over the Steelers at the Kingdome, as the defense intercepts three passes – including one that Dave Brown returns 18 yards for a touchdown – and linebackers Fredd Young, Keith Butler and Greg Gaines combine for 26 tackles. Dave Krieg also passes for two touchdowns and Curt Warner runs for 114 yards.

2003 – The Seahawks post their first season-opening victory at home since 1986, 27-10 over the Saints as Shaun Alexander scores two touchdowns and linebacker Anthony Simmons paces the defense with an 11-tackle performance.

But it has happened only once since the 1996 season that we examined in the eighth installment of our series of seasonal recaps. That was in 2001, when the linebacking trio of Anthony Simmons (123), Chad Brown (106) and Levon Kirkland (101) turned the trick.

Since then, the only time the Seahawks have had two players do it in the same season was in 2009 – when linebacker David Hawthorne (116) and safety Jordan Babineaux (106) each did it for the first time in their careers.

Here’s a look at the other triple-digit tackling trios in franchise history, as well as the two seasons when five players each produced at least 100 tackles:

1976: Free safety Dave Brown (111), linebacker Mike Curtis (107), middle linebacker Ed Bradley (101).

1978: Middle linebacker Terry Beeson (club-record 153), linebacker Keith Butler (122), linebacker Sammy Green (115), cornerback Cornell Webster (113), free safety John Harris (113).

1980: Linebacker Michael Jackson (136), Harris (119), strong safety Keith Simpson (110), defensive tackle Robert Hardy (103), Beeson (101).

1981: Jackson (141), strong safety Kenny Easley (107), Butler (100).

1993: Free safety Eugene Robinson (111), linebacker Terry Wooden (106), middle linebacker Rod Stephens (105).

1996: Middle linebacker Dean Wells (107), linebacker Winston Moss (106), strong safety Robert Blackmon (102).

2001: Simmons, Brown, Kirkland.

And, speaking of tackles and trios, five players have led the Seahawks in tackles for at least three consecutive seasons: Beeson (1977-79), Jackson (1980-82), Fredd Young (1985-87), Chad Brown (1997-99) and Lofa Tatupu (2005-08).

Robinson also did it four times, but not consecutively (1988-89, 1992-93); while Simmons did it three times, but not in a row (2000-01, 2003).
