Yes, I can’t remember who (maybe the 9), but one of the smaller Titans chopped a hard-running TPJ down close to the try line because he simply drove his shoulder in at the waist. Why? Because he had pride in what he was doing, it meant something to him.
Sure, there is every chance you won’t stop a hard-running bloke who is 20-30kg heavier than you, but you at least try.
And another thing it does; your teammates appreciate you a lot more if they see you picking your trampled body up of the grass after being dusted by a rampaging hulk than if you simply watch him past you to score.
