Even Trade Seattle acquired William Sandifer / Bill Sandifer from San Francisco 49ers on 1977-05-03, sending Ed Bradley (W.) in return. This transaction fits Seattle's broader roster-building record for 1977: targeted asset movement, limited known aftershocks, and no obvious franchise-altering result. The Seahawks' C grade is tied to receiving William Sandifer / Bill Sandifer while parting with Ed Bradley (W.). San Francisco 49ers's side is graded C because the exchange appears roughly balanced from the available record.
