With a little work / GM skills, you could find a forward to put up 41 points a season AND give an effort every night. For considerably less what he is making on his long term deal. He is getting treated like a superstar without the superstar play.
It's not 2008 or even 2010 any more. Mule has been a middling player for a while now, not great, not total garbage, the frustrating thing is knowing what he is capable of and not getting it consistently from him. Frankly, I'm done with him.
