There were a lot of rumors that Rodgers has kind of went rogue the last couple years. He is a great QB, an all time great, but if true, he caused a lot of the problems on offense too.
I wouldn't love the hire of McCarthy if true, but he was a good coach for years. I don't fault him entirely for the defenses he fielded because he didn't draft the players. Notice that the GM was fired last year and they haven't been as good because of the roster. Dorsey is known as a great talent evaluator, so the talent should be there.
