You deliver a hit like Murphy did, there will be some heat coming your way the next time around. To expect anything different is beyond delusional. If Hedman (or anyone) delivered that hit you're damn right he'd have a target on his back the next time the two teams met.
I mean, maybe Collition would have a case if Murphy got jumped or hit with something dirty (could you imagine if someone on TB laid the exact same hit in response? What would he say then?) , but the guy got challenged, players finished their checks on him, and he took a few chirps. Nothing out of the ordinary at all, a very typical response for any team that gives a damn really. His comments make Chicago seem soft, I doubt most of the players even want to see him say that.
