Including the 30 Dec final ranking and the 22 Oct version, the computer ranked Seattle No. 1 seven times. Seattle was also No. 1 in the final preseason rankings, 26 and 30 Aug. In the just completed playoffs, No. 11 San Diego “upset” No. 10 Cincinnati. The other 10 playoff winners were ranked higher in the final/pre-playoff computation.
In the first, and only published, NFL pre-playoff computation, the Redskins were No. 1. No. 8 San Diego “upset” No. 7 Pittsburgh. The other 14 January 1983 playoff winners were ranked higher.
