Here is what I know. Kyler is not better than Josh Allen, Joe Burrow, Lamar Jackson, Pat Mahomes, Justin Herbert, Jalen Hurts, Jared Goff, and Matt Stafford. So that puts him out of the top 8.
Kyler is having worse or similar statistical seasons to Bo Nix, Jayden Daniels, and CJ Stroud despite those other three all being in their first or second seasons, and theirs teams also having a better record. I don't think he really belongs in a conversation with these players because it is more about preference and how you view the gap. You could argue a preference for Stroud whose down year in tear 2 is still statistically better than Kyler's year this year and so you would prefer the upside of Stroud.
Kyler is having a worse or similar statistical season to Baker Mayfield, Russell Wilson, Geno Smith, Jordan Love, and Sam Darnold and those QBs are producing a similar team record or better. Love is kinda a weird inclusion in here but I look at it as at age 26, he is more vet than not. Kyler fits in this group IMO. These players are all kinda established (outside of Darnold) as to what they are.
None of this factors in Tua, Brock Purdy or Dak.
How you "rank" these guys is tough but I would disagree with Kyler being even in debate as a top 8 QB without significant improvement.
