I said a lot, but I know when I was young, I remember a lot of sports writers would talk about old teams like the Browns and call them the Champions.
Before the AFL came along...it just wasn't called the "Super Bowl" so of course they weren't called "Super Bowl Champs" but they were still...
That list is nuts..it's crazy that so many teams have never won it...but if I'm not mistaken, Cleveland won 4 NFL titles in the 40s and 50s and I think a lot of folks count that the same as a Super Bowl.
