That could be said for any professional sport, I agree that it just brings more excitement to the game, but it needs to be done with taste.
There is always a few that take it too far.
What other professional sport dances around like a fool when they score? I haven't seen any. The closest I can think of in any other sport celebrating a score is when they pump their fist after a score and maybe a few guys on his team pat him on the back. That's a far cry from dancing a jig for 30 seconds. If you can think of one please enlighten me.
Can you imagine basketball players dancing a jig after each score? That'd sure cut down on scoring time.
