I have no problem with Dak's ranking.
To me what separates 1s from 2s is consistency. I know the contradiction there is Mahomes started last years playing very poorly, but when it counted he returned to form and carried his team. Dak was the opposite. He started out playing like the MVP, but finished the years stumbling to the season end. I do not consider that last game against the Eagles to be anything more than stats padding.
I am not a Lamar Jackson fan, at least not in the sense of ranking him in the TOP QBs in the league. Let's be honest, he is a RB playing the QB position. His passing skills are so-so to me. It is hard to put him with some of the better throwers in the leave.
I might get some flack for this one too, but I think Herbert and Burrow are better than Josh Allen already. Allen has improved since his rookie season, but Burrow and Herbert are still better right now. I am not saying Allen is not tier 1, although I think it is close, just that he is a tick lower than the other two guys.
