Pretty simple, so long as it is not prohibited contact (high, hold) you can push all you like, so long as you get back to the ball. If you bulldoze an opponent t off the ball and then you don’t get to the ball, that’s a block.
I see him as similar to Bryan before Bryan added a heap of kgs (yes, he’s still no monster but he’s much stronger than when he started). I think he (VV) might end up similarly useful in about 2 years. Hopefully not much longer than that. But really he’s being played early.
Like that one last night whare they both had there arms around each other, but the umpire paid a free kick against Vigo and the Giants ruck kicked a goal?
(The umpire may have paid it for high contact or something else. Not sure, but it didn’t seem right at the time.)
He had his right arm and hand over the shoulder, that’s what the ump paid it for.
It was technically there but they only sometimes penalise it. The umps are very inconstant with what they allow and don’t allow and often the players themselves have no idea whose free it is.
That definitely used to be the case. Just ask Sean McKernan. There was one game where he gave away 6 or 7 free kicks for blocking. Whether or not the rule has changed, who would know.
