Don't need to throw punches. The Video tribunal has made that too damaging. But by all means hit your opponent in a tackle, shepard, spoil, as hard as you can. Add that extra bit of power and aggression each time it's body on body and we'll start to be respected.
I didn't like Lids flaying his arms last week. Sure, it was good to see agro but he could have lost the free and been reported. Would have rather him grab a handful of jumper, let the bastard know that the next time he's near the ball he's going to hurt, then deliver on that promise.
