I’d put him more in the 8-10 range.
Mahomes, Allen, Burrow, Lamar, Stafford, Herbert, Dak, cousins, then purdy, Tua, Lawerence, hurts. Maybe Goff before Tua and Lawerence.
It's only his 2nd season and he plays on a loaded roster of talent so I have a hard time narrowing down where to rank him. I think Mahomes Allen Burrow and Lamar are top 5 without debate. Talent wise Herbert is right there too but his team stinks right now. Stafford has been hurt a lot lately, I view him more towards the lower end of the top 10 at this point. Dak and Cousins are good regular season QB but have had their share of choke jobs in the playoffs so they are guys I have a hard time putting in a top 5 lineup too as I don't view them as elite QB. Tua and Lawrence are still pretty young but have had some success.
If Brock wins the SB this year I probably have him in that 5-7 range for top QB in the league at the moment but regardless he's definitely in the top 10 as he's already surpassed the playoff success in just 2 years that some of those guys listed haven't done in quite a few more appearances.
Just going to take a shot at a rough categorization of the QBs right now without putting an actual ranking number to each guy.
Tier 1 : Mahomes is in a tier of his own
Tier 2: Allen, Burrow, Jackson, Hurts
Tier 3: Purdy, Dak, Herbert, Tua, Lawrence
Tier 4: Cousins, Stroud, Stafford, Goff
Stroud is a guy I think is one to watch as could see him moving up the ranks quickly. Crazy to think Goff is back in the conversation as one of the better QBs in the league as most have written him off but Campbell and his staff have done a nice job of building him back up from his rough ending with the Rams.
