Well it's easier to take when the team is winning
However when the team sucks and the $50 million quarterback is not putting up $50 million stats or winning , it's easy to point the finger at the douchebag who's making other players yell at him.
Look at Aaron Rodgers, he comes across as enormous douchebag, but he is a winner
I guarantee you if he's putting up the numbers that Derek Carr was putting up, not many people would put up with his attitude.
It's as simple as that.
