Just went and watched these incidents after reading this thread as I found it quite interesting. I have no bias towards either team - but @RTG20 you're saying that the ref didn't realize it was worthy of a yellow. That's clearly not true, if you watch the moment Blind commits the foul, the ref is getting ready to blow and pull something from his pocket right away. That seems like a clear indication, that he was already giving Blind the second yellow, and thus should have never let the play continue.

Big, big mistake really.
