What makes those guys elite is the fact that when they are on the field they have to be accounted for because they always give their teams a fighting chance. Mahomes is that way as well. No one can claim that about Dak.
The main takeaway from this article is Dak doesn’t perform against good teams. Other QBs still have high TD/INT ratios and the like, while Dak is basically right there with Jared Goff.
Dak’s Senior year in college was the same exact story in Dallas, with four losses to ranked teams, the only win against ranked team was 25 Missouri, while Ole Miss was 24 and against the other ranked teams Dak only put points up on the board with in garbage time 4th quarter while getting blown out. When he gets out to a big lead against an over-rated teams and bums, he puts up numbers which inflate his stats.
Like you said, you don’t have to account for him, if you have a quality roster. Make him into a passer and have to go down his reads, he looks like a bottom-tier QB.
