I completely agree with Ogre and Shady on this one. I understand the whole "message sending" angle, yeah. But fighting after a clean hit is weak. I like big, well-timed hits, ya know? It's a big part of the game, for me. Obviously I don't like seeing one of "my guys" on the receiving end of a hit like that but I was always taught to be aware of your surroundings and who is on the ice. "Keep your head up," essentially. If you get caught admiring your own pass or something similar... that's on you.
There is also a "fog of war" aspect going on, though. **** happens fast.
Things also aren't always neat and tidy, either. The Reaves hit, for instance. The first thing that popped into my head was "What a dumb suicide pass... who was that? *sigh* Disco magic at work, again." Not "GO AFTER REAVES, YOU PANSIES!" That isn't on Crosby or Reaves, IMO.
