I threw a new poll up on the right - vote on it - curious to see who everybody thinks is the most disappointing this year. I excluded the guys who have missed significant amounts of time to injury like Savard and Lucic, but you could certainly make a case for them too. In fact, you could probably list the entire roster aside from Bergeron who may be the only player to have exceeded expectations this year.
I just went with the 5 players I think have been the most disappointing. My anti-Wheeler bias may be showing here a little too; but I think Wideman, Ryder, and Hunwick would make just about everyone's top 5.
