I mean the odds, prior to his Bills game, had Dak as favorite (I remember because I made my bet on Lamar to win MVP shortly before that game because I do not think T2 QBs win MVP because the voters are looking for a reason to knock you down). The debate for Purdy was "is it Purdy or is it CMC" so he had no shot and everyone knew which is why just about every single talking head had Dak has the MVP, and the oddsmakers followed, many, and this was hilarious to me, calling his 8 game run "one of the best in NFL history by a QB". If the season ended prior to that Bills game he has MVP locked in, but then he played bad against the Bills and the next week Purdy was bad against the Ravens and then Lamar stomped and was dominant against the Dolphins and that was the end of the conversation.
