Eh, I don't mind the players policing themselves to an extent out there.
Xhekaj is a throwback to the era of 'if you hit my star, you fight. If you don't flght, I go after your star'.
I remember when Peca famously caught Selanne for a hit that made him do a full flip and fractured his orbital bone and Tie Domi was caught on a hot mic saying, "Next game, don't dress Pavel. Don't dress Pavel next game".
I think cheap shots are bad and should be litigated out of the game as much as possible. But if this reduces rats who cheapshot stars and then hide behind refs, I don't mind it. Hockey is a man's game afterall (not meaning this in a misogynistic way).
