Totally agree about the Sabres logo. Boooorrrrrrrrinnnnnngggg. A good logo is a simple representation of a theme. Not pictures of the literal items comprising your team name. The best logo the Sabres ever had was actually the buffalo head they wore with black and red. No effort or professional work at all was ever involved in creating the original one.
Why does everybody have such a boner for the original Sabres logo? It's awful. It'd be like if the winged wheel was a wheel set above a set of wings floating around in a blank void haphazardly slapped together in a circle.
Also, the Jets' new logo looks a bit CHL-ey, but it's by no means among the worst in the league. I think the wordmark of all things looks pretty sharp, actually.
The original Jets logo was only slightly better. Good job: the word Jets with a hockey stick for the J. The new one is sharp and I like the wordmark. Don't much care for the crossed hockey stick logo, but the one with the plane is good, and the whole thing, colors and all, is very Air Force-y. Which is a much better theme than what appears to be a passenger liner on the original one.
