Fair enough if that was the case - on the field refs do make mistakes. And Leeds fans will no doubt quote the Wigan try from the DW game that Wigan won 26 - 24, that came after a blatant knock-on by Smith. That was an incorrect decision but could not be referred to the VR as it happened in back play.
The difference here is that the VR yet again came to a decision that the vast majority (90%?) would disagree with. This has happened a lot recently and, dare I say it, Leeds seem to have been the beneficiaries more often than not.

I can honestly say I said the same as Clarke, two points could have quite easily given them the field position advantage from the kick off

I think virtually everyone where I was sitting thought the same. The sense of relief was palpable. To be honest, this doesn't say a huge amount for Clarke's perceptiveness, it's more an indication of a lack of it by Stevo and Eddie. That said, I reckon Clarke is a fairly decent summariser when he's not over-exhilarated by unfolding events on the field, a trait that's less and less evident these days.

Out of all the teams in SL & NRL realistically who wouldn't have gone for 2?

I think the field position after taking 2 points is a bit of a red herring. I think Leeds were looking at a repeat set near a tired opponents line and we're trying to kill the match by scoring a try. Right call for me.

Clarke has a knowledge of RL that should make him an asset to Sky's coverage on a par with Jon Wells and Brian Carney. I don't expect commentators not to follow and be passionate about a team. But I do expect them to be professional enough to kerb their bias whilst on air to the extent that their commentary doesn't oscillate between denigrating whom ever Wigan happen to be playing and creaming over how good Wigan are. If he can't contain his loyalty and blind passion for Wigan he should jog on and get a job in their marketing team or with their cheer leaders.
