Racking up stats in advantageous situations, when the Browns are in positive down/distance and off play action is very important to any NFL offense and I don't want to take that away from Mayfield. He's done a good job in those scenarios for the most part, perhaps not as great as we'd want, but good enough.
But the fact is Mayfield has just not been a good QB this season when he isn't in an optimal position and that is the one element offensively the Browns really are lacking.
And that is also the very clear separator between Mayfield and the much better QB's in the league.
Herbert wasn't perfect today, he missed some easy throws, but there was never a down and distance where I felt like there was no chance of him converting. I have very little confidence in Baker converting any third and medium to long.
