6. Rochester Griffins (1974)
The Rochester Griffins only played for a season, but man, did they make the most of it count. The Griffs won the inaugural championship in the original NLL. Despite calling it quits after just one season, their logo always seems to be a fan favorite when the retro logo conversation comes up. I think this logo could easily be used in today’s league and I was curious if we would see it resurface when the original Knighthawks moved to Halifax. You could definitely put this one in the timeless category.
