The biggest casualty of the NFL 2002 realignment was the heated Raiders-Seahawks rivalry. Though it lasted only 24 years, somewhat short by NFL's standards, it was an intense series that produced numerous memorable games.
The expansion Seattle Seahawks came into the NFL in 1976, and after two years in the NFC, it was moved over to the AFC West, joining four former AFL franchises that also included the Broncos, Chiefs and Chargers. It didn't take long for Seattle to hate all things Silver and Black, and in a short amount of time that enmity rose to equal or even surpass the level of the Raiders' more historical rivals.
Between 1978 and 2001, before the Seahawks were moved back to the NFC, the teams met 49 times, with the Raiders holding a 26-23 edge. They met twice in the playoffs: after the 1983 season when the Raiders beat the Seahawks in the AFC title game at the L.A. Coliseum en route to their Super Bowl XVIII victory; Seattle returned the favor the next season, ending the Raiders' repeat quest at the raucous Kingdome in an AFC wild card game.
But the most memorable contest between these rivals was a Monday Night game in November 1987, when Bo Jackson scored three touchdowns in a 37-14 Raiders rout at the Kingdome. But after realignment consigned these teams to meet but once every four years, this rivalry is now relegated to only history books and highlight reels.
