The thing is he was clever about it. Held down too long and there's no choice, by letting him play the ball and attack the dummy half, your at least giving yourself the "oh I was just over eager" argument - which leaves the door open for the ref to just leave it at the penalty - it's not like warrington had been dominant in the sets leading up, and just caught us cold on the flank which also affected the decision.
We haven't had a player that's irritated opposition fans this much since Hooper, it's been way too long
