I always wear my blue nords jersey to games...
Every single playoff game I've ever been to they've provided white pom-poms. I think that's enough. Unless they get it published in the news paper or put it on the evening news it won't get a good turn out anyways. A majority of those people in the arena don't read hockey blogs or forums I'm sure.
If it gets super hyped before, I'll participate, but at this point it doesn't seem like many people will so I'd rather get decked out in my Avs-gear, none of which is white
I'd go all blue. Phoenix and Pittsburgh already do white out's Philly has Orange and the Caps own Red (which is close enough to Burgandy). I'd do something semi-unique. Besides the Avs will have white pom-poms.
