Actually CNN ranks 83 redskins offense fourth best in the last 25 years, NOT best of all time.

"Joe Gibbs had already won a Super Bowl, but it was in '83 when he established himself as an offensive genius. The Skins scored 541 points, the second-highest total ever, and finished 14-2. Washington had an unstoppable power game with John Riggins and Joe Washington running behind one of the greatest offensive lines of all time. And the Redskins were dangerous in the air, with QB Joe Theismann throwing to Charlie Brown and Art Monk."
