I like how those idiots are called Football Team, it's like for punishment for being racist they get to be default. Should just leave them as Football Team for their generic ass asses. Don't even deserve a name.
I don't think teams specifically get biased calls. I do think certain plays get calls others don't. I think that is where ref bias really shows itself the most. I don't consider crews that call certain things heavier than others bias. You see that a lot too. But that is part of coaching, knowing what crew is calling your game and their tendency....and you should know that and play to it.
