This must be all time not this season and I have no idea why stats from prior years have any implications for this year's MVP.
Here are Daks stats against teams with winning records this season:
New Orleans - 22-33, 67%, 223 yds, 1 Int, QBR 73.2
Green Bay - 27-44, 61.3%, 463 yds, 2 TDs, 3 Int, QBR 83.8
Minnesota - 28-46, 60.8%, 397 yds, 3 TDs, 1 Int, QBR 101.5
New England - 19-33, 57.5%, 212 yds, 1 Int, QBR 64.2
Buffalo - 32-49, 65.3%, 355 yds, 2 TD, 1 Int, QBR 91.8
That New England game in that weather was a problem for both QBs and only 1 TD was scored in the game.
I am not suggesting Dak belongs in the conversation for MVP, the kid in Baltimore is way ahead of Dak in that race, but Dak has not been all that bad in games against winning teams this year and certainly not a QBR below 50. That is total BS. Unfortunately, Dak had a terrible game yesterday and it was not measured in stats, which were okay. Dak looked off yesterday and that is not in dispute.
