I thought he was very odd.
On the plus side, he did try to play advantage a couple of times quite well and did spot some players nudging others when they were in the air.
On the negative side, he was bloody useless at everything else! Not help by an inept lino, but he didn't stamp his authority on the game until too late and then was inconsistent - a couple of players should have had a second yellow and one should have already been given a yellow for a previous challenge. Didn't stop players kicking the ball away, easily conned.
I'll give him a 2, but only because I am saving the 1 for a ref that is not only awful but makes a number of truly game alterign wrong decisions!
