I feel bad for Karlsson. He's not even hiding that he's injured, and I agree, at what point do you say "You're not playing." I mean, he's playing for a contract right now and I think this past season hurt his value. What team would want to shell out what he's asking for an injury prone player. He hasn't really ever been the same since the playoffs two years ago when he was playing with essentially, a missing foot. On the flip side, usually when Karlsson's on the ice, they are a better team and he's leading in points for a defensemen in this year's playoffs.
I just feel bad for him.
EDIT: Well, I guess we just found that point
