I actually really like the idea of them...not necessarily the one shown above, but don't think I'd want to see them for 41 games a season. Personally, I'd like the off-white sweater with burgundy lettering "Colorado" written down diagonally across the front. Basically invert the old thirds but use the off/dirty white.
If they do use one of those color schemes though I would hope to see them incorporated as a winter/stadium classic jersey...and depending on how they looked on the ice they could be elevated to a third jersey status. I think it would be cool to have a white (road) alternate jersey instead. Don't think any other team in the league uses their thirds for away games.
Of course, I really would like to see the NHL shift back to whites at home and dark sweaters for the road but that's a whole other conversation.
