The Seattle Seahawks were founded on June 4, 1974 when the NFL announced Seattle would be awarded a franchise that would begin play for the 1976 season. The 1st head coach in club history came from the Vikings- Jack Patera, who was hired on January 3, 1976. Patera served as defensive line coach on Bud Grant’s staff from 1969-75 where he was an architect of the Purple People Eaters line. One Vikings mainstay from the early 1970s, Bob Lurtsema, was part of a Vikings trade in 1976 when WR Ahmad Rashad was acquired from the Seattle for Lurtsema and a 4th-round draft pick.
