Not going to be popular with this opinion but we would be too. I have seen too many thread about refs and inconsistent calls and we got away with one honestly. I am so surprise they didn't call that one. Base on my understanding, he may have hit him with his shoulder but any contact to the other player's head or neck will always, regardless if you lead with your shoulder or not, will draw a flag. That should of been a flag. Down vote it if you want but you know if it was the other way around, you guys would be furious too.
