The reality is that the Packers were at home with a QB that's the back to back MVP. Watson is a mismatch WR and it was likely a matter of time before he had a breakout game - he has had niggling all injuries all season but people just want to make sweeping statements. It was also a must win game for the hosts.
The defense underperformed but they still forced a number of turnovers in fantastic field position for the offense.
Occasionally the defense will give up more points than is ideal in which case if you have a QB being paid the big bucks then he needs to show up and justify it when it really matters. Unfortunately Prescott was unable to do this yesterday despite the offense having multiple drives to win the game.
People can criticise other QBs and yes Allen has had an awful couple of games - he was the main reason for the Bills losing yesterday and Rodgers had a poor game against the Lions largely contributing to their defeat. However, they have a load of credit in the locker, particularly Rodgers, in carrying their teams to countless wins. When was the last time Prescott did that or is it indeed the case that his impact on a team is basically the same as that of a Tannehill or Carr and barely even a Cousins!?
