I thought he did ok, though he probably needed to bin someone for the lack of discipline earlier in the match. Catalans are consistently the least disciplined team in the league so there was always going to be a ton of penalties going to happen and then add Wire's total collapse into the equation and methinks the ref might have felt it was a lost cause by about the start of the second half. (Much like Wire really - what is it with them? Their opposition fights back so they give up and die)
He lost control of the game and probably wasn't used to that kind of match which SL refs are used and it was a bit of a scrappy affair. He should sent Westwood off, might have kept a bit of a lid on it.
