I don't think this requires a whole lot of scrutiny. The Sabres logo obviously is a much better-looking logo than the Lightning's. If you need an explanation, try and see past all the words in the Lightning logo. Bet you can't.
You know, metal is a good conductor of electricity. Still, a bolt of Lightning would fry even the toughest of Sabres.
All this time I've been saying that the logo for a team called the "Sabres" conspicuously lacks, you know, a sabre. Turns out, I've been wrong all this time. A reader here recently pointed out to me that there is in fact a very subtle sword across the side of the buffalo. The white horn is the handle and the blue stripe protruding from it is the blade. I think that's really cool. However! It's the name of the team. It shouldn't be subtle. It should be right out there in the open. Make the buffalo subtle. At least there's a lightning bolt in the Lightning logo.
