I explained it to you. It involves just a little bit of brain power on your part, so hopefully you can crank that mouse wheel up in your head.
The first three QBs picked for the Pro Bowl were Rodgers, Brees and Goff. So now according to your belief that Pro Bowls are huge deals, the fact those three were the first choices means they viewed Dak as having a season not as good as those three. So, right now, he ranks 4th in the NFC in QB performances based on the Pro Bowl voting.
Rodgers had to bail out because he was hurt. The Pro-Bowl didn't turn to Dak to replace him. They went with Wilson. So Dak was viewed as not having as good a performance in 2018 as Wilson. Therefore, the Pro Bowl viewed Rodgers, Brees, Goff and now Wilson as better. Goff then had to bail because he was in the SB the following week. The Pro Bowl didn't then go to Prescott to replace him, they went to Trubisky. So, taking all that into consideration, the Pro Bowl viewed Prescott as the 6th best QB in the NFC. They deemed Rodgers, Brees, Goff, Wilson and Trubisky to have been better QBs in the NFC than Prescott.
So he was 6th in the NFC, at best. Are you going to argue he outperformed the AFC QBs such as Mahomes, Luck, Watson and Rivers?
