Jackson>>>Mayfield, I can't really see much argument for Mayfield. Jackson has shown a far higher ceiling and floor. Now NFL wise, I think a case could be made for Mayfield, but fantasy wise, not even close. I have Jackson as QB3 in dynasty. I think people are forgetting how great he can be, which has been at times this year too, as he was the #1 fantasy QB in weeks 14-16.
Prescott>>>Rodgers, the age difference is a big deal here. Its possible Rodgers is the better QB in 2021, but even that is a maybe. Dak is younger, and has better weapons, assuming he stays in Dallas which feels like a 95% chance.
Murray>>>Watson, this is another one, where NFL wise, I'd prefer Watson, but fantasy wise, Murray's rushing is so much higher that its hard to make a case against him that isn't about durability. I never like projecting injuries, so barring that, I think Murray has a much higher ceiling, and an equal floor.
Herbert>>>Lawrence, again, I'd rather have Lawrence as an NFL QB, but he may never have the weapons that Herbert has right now. Factor in that we've seen Herbert do it on the NFL level, and I'd take Herbert.
Goff>>>Trubisky, I don't think Trubisky is an NFL starting QB, possibly as soon as next year. Goff has shown a higher ceiling and floor, and is tied to McVay. You'd like to see more consistent play from Goff, and he may simply just be an average starter, but that is more than I can say for Trubisky.
Burrow>>>Tua, Burrow was QB12 before he got hurt this season, and that was mostly without Mixon and with likely the worst version(because he'll only get better) of Higgins he'll have. I do like Tua as an underrated QB2, and he has a lot of upside, but he's got more question marks as well.
