That is a pretty bad precedent imo.
Regardless of who it was or who he plays for, that sort of action should be more than just 2 weeks. He knocked a player out that basically wasn't ready for any sort of contact.
How would we all react if a Carlton player did the same action to Dusty and only got 2 week?
Didn't Rance get 2 for nothing more than just a forearm slap on Watts?
