Chicks and their Polls: Trade Bait

As the trade deadline draws ever nearer, the rumors grow ever louder. There is still no indication as to whether the Avalanche will be buyers or sellers this season since the team's playoff status isn't totally clear. What is clear is what the Avs need: a top six forward who can score goals. To get something like that via trade, however, you have to give up something like that as well. There are some universally acceptable untouchables on this team although the list is pretty short. Most people would consider Matt Duchene, Erik Johnson, Semyon Varlamov and Gabriel Landeskog as the only true non-negotiables. But which player is the most negotiable?

(Please note that a deal would necessarily include more than just the players listed in the options.)
