 The franchise began play in 1976 in the aforementioned NFC West but switched conferences with the Buccaneers after one season and joined the AFC West.This realignment was dictated by the league as part of the 1976 expansion plan, so that both expansion teams could play each other twice and every other NFL franchise once (the ones in their conference at the time) during their first two seasons.The Seahawks won both matchups against the Buccaneers in their first two seasons, the former of which was the Seahawks' first regular season victory.
