This Free Press story from 2015 has been cited before & holds no weight against the video evidence that exists and the actual newspaper stories from the era where no mention of wearing white to games ever occurred. Six years ago Kirby took a lot of heat for the very article you are quoting.
If you have a library card its easy to log in to the newspaper archives and search for key words or take the time to read the sports coverage for a few weeks.
I have. There's nothing there.
I was in grade 10 in 1985 & as a big a fan of our Jets as anyone. If any push was made to wear white I'd have been covered from head to foot in white garb. Family pictures of friends over for games or shots of us as we went out to sit in our cheap 7-11 seats a stones throw from the Queen's face have us wearing Jets garb of no particular colour.
Fast forward to 1987 & its a sea of white.
I do however remember the "Good Guys Wear White" tag line. When I get home & have some time I'll throw that into the Newspaper Archives search engine and see what comes up. There will certainly be a reference to it where it'll be simple to ascertain what year that slogan originated.
