I’m always bummed when teams ditch their logos in favor of new, more fashionable ones, because the only way the great, timeless logos got that way was through decades of permeating the culture at large and the years worth of associations they’ve accumulated. I mean, the Broncos’ old D-with-prancing-horse logo was hardly a classic from a purely design perspective, but it was well on its way to achieving icon status just because it’d been in use for so long; think how much more resonance Elway’s first Super Bowl non-choke would’ve had if he’d been wearing the same uniform as before.
All that said, I’ve been looking at the Seahawks’ helmets for more than twenty years now, and they still look just plain weird.
