While I agree that changes have to be made this offseason there´s absolutely no reason to move on from McCarthy.
McCarthy is highly successful as a play caller. He gave it up at the start of the 2015 season and the offense struggled. The unit improved again this season with MM taking it back.
They were 6 and 0 with out Mm calling plays.. Rodgers hurt his knee in charger game and his mechanics suffered.. He couldn't plant properly..
Well documented last year
