The states were robbed clear and simple, still I think they will go through.
Not really - not if the whistle was blown for the shirt pulling and I can't see any other reason, having watched it several times now. The shirt pull was the only infringement I could see that happened before the ref blew up.
As AWB said though, the ref could have made it clearer. And it is quite possible the ref missed the shirt pull (although the two players were the nearest to him, so would have been hard for him to miss) and the reason he actually gave remains a mystery!
