Childs' performance has been utterly farcical to be honest. The red card was not only a shocking decision, a massive over reaction to a clumsy challenge, but it came minutes after an almost identical (And even more deliberate) attack on the head of the Widnes kicker.
He's consistently given decisions Wigan's way, only he will know if that's incompetence or bias. I'm liking the first option, like most of the referees in Super League they have no common sense, no judgement and are weak individuals. Some of the decision making has been horrific, but it's the lack of consistency that is the problem and is what frustrates players, coaches and fans alike. If they gave the same decision for each instance, people would know what they could do, they would know how to behave. Instead everyone is left confused as he rules red card for Widnes, yet ignores identical tackles the other way.
He could have single handily decided the outcome of the game tonight. Widnes would have won this game comfortably if it wasn't for the referee and yet Wigan are currently winning.
