If you were to put the two logos out into the average sports community, most wouldn't even know what the hell the Hurricanes logo is, let alone what team it is.
At least with the Blazers logo, fans recognize it and know it.
As for being "meaningless" to every non Blazer fan, they at least would know what it is. You ask the generic non Hurricane fan about their logo and they probably wouldn't have a clue what it is, or what sport it's for, or better yet, that it's an actual real logo.
I'm not saying their logo is bad, but it's not even a top 10 NHL logo. Hell, it's not even the best logo in their own state.
