Football is 2 halves. Wentz and the entire Eagles offense did nothing in the first half, because we controlled the clock and didn't let them. In the 2nd half, he threw 3 TDs and capitalized with points off the turnovers his defense gave him. He's not the reason they lost that game.
I agree that Dak takes way more criticism than Wentz for every little thing, and I still say that the fact that the Eagles team was so good last year that they went on to win the Super Bowl with Foles after Wentz went out proved that Wentz wasn't the main reason they were having so much success last year, even though he was playing very well.
If Dak's rookie season was only good because the team around him was terrific, then 2017 Wentz could get the same criticism. This year you're seeing how Wentz does with a not that great team around him comparatively. 2018 Wentz is not that different from 2017 Dak.
2017 Dak - 27 TDs, 13 INTs, 3 fumbles lost.
2018 Wentz - 21 TD, 7 INTs, 5 fumbles lost. 3 games left, so he projects to 31 TDs, 13 INTs, 7 fumbles. Basically Dak's season last year, with 4 more TDs, and 4 more turnovers.
