In that loss to Mahommes, I never heard anyone anywhere provide anything but glowing remarks on Josh Allen. Granted, since that game, he seems to have stepped backwards and has had an issue with decisions and turnovers, but in that game, he was "crowned," yes, in a loss. That performance is what stirred up all the fuss about overtime rules in the playoffs because people wanted to see more in that game due to how great the two QB's played. I'm not giving him anything, just explaining why most QB rankings aren't just based on Wins and Losses. If one team wins with a moderately talented QB, that QB isn't going to suddenly be ranked at the top of the QB list.
The Lions beat the Chiefs; Goff outplayed Mahommes in that game. But no one is ranking Goff ahead of Mahommes.
