Home advantage also helps.

Nobody in the pub I was at in Warrington thought that Watkin's try was put down cleanly and howled when it was given.
I have to agree with them but said nothing as it would look like sour grapes.

It wasn't put down cleanly, if by cleanly you mean that he was in full control of the ball and grounded it with his hand? So that's true. He did have fingertip control - well, as much control as you can have with your fingertips - and had downward pressure with 1/2 fingers, which as per the rules is all you need for a try to be given. I see the annoyance with a try like that, but the correct decision was given.

These things happen in every game; we just tend to dwell on them a lot more when it's a big game.

No I didn't mean that - I meant it appeared to be fresh air between the ball and his hand as it went down.
Certainly the sky mob had serious doubts.

Still its all history and I wish you good luck against the pies.
