What you see up there is taken from a VHS tape called Hail to the Redskins and produced by NFL Films in 1986. It's a compilation of highlights from the 50 seasons following the team's move to D.C. from Boston.
The video played a small role in the U.S. Patent and Trademark Office case that on Wednesday saw the cancellation of six of the team's Redskins trademarks, on the grounds that the team name is "derogatory" and "offensive." The plaintiffs had entered Hail to the Redskins as evidence, and it's not hard to see why. The 22-minute film, made during the glory days of the Joe Gibbs I Era, has not aged well. Significant chunks of it would seem ridiculous today even to Redskins dead-enders, and watching Hail now is a pretty good reminder that sensibilities change, even if nicknames don't.
