Hey folks, infrequent poster here, but I always appreciate the help.

I have an opportunity to acquire Kevin Shattenkirk for nearly nothing, but I'm wondering if he's an upgrade over anyone on my current roster. I have to drop one of: Fowler, Yandle, Goligoski, or Campbell in order to fit him in.

League tracks: G,A, PPG, PPA, SHG, SHA, GWG, H, S, BLK, and gives a negative .5 point for each PIM.

Is Shattenkirk an upgrade here?
