I did tend to think the ref was out of his depth a touch, I personally was calling for a yellow to Chiefs in 1st 40, and particularly the loosehead prop, mind you he seemed very reluctant to penalise either team for coming in side of maul, and both teams were guilty numerous times. Actually thought it was right call for obstruction as the Bulls player actually spread his arms, was not needed as Retallick was probably never going to get to player anyway. Was interested to see when TMO talked ref out of Red card which I thought it was. Also maybe an elbow to face may of been looked at, and player that accidently kneed ALB in head probably has to be a little careful, I like everyone could see it accidental but some refs may look at it as dangerous. All in all Chiefs were probably lucky, and they certainly relying on a few players at moment to do a lot, I thought D Mac, Sam Cane, Retallick were huge in the game.
I will also add with all the penalties in first half , is probably one of the fist times I have watched a game and thought if you don't improve your discipline in 2nd half Chiefs, I will cheer for a non NZ team.
