He's just been snakebitten (how many posts has he hit this year?), injured, and affected by slumping/ injured Sedins. He's going to break out at some point.
He is still working hard and doing a lot of things that create chances/ goals for teammates. There have been a number of goals scored where he has been screening the goaltender - basically creating the goal without even being credited with an assist.
The coaching staff recognizes that he has been doing a lot of positive things that don't show up on the scoresheet (Torts has said as much to the media) and he is being given quality minutes as a result. Plus he is, by all reports, a great team guy.
It's way too early to conclude that he is over the hill and it's ridiculous to suggest trading him for nothing simply to get rid of the contract.
