Right or wrong, I think Bills fans dismiss how much the INT's hurt is rep. The best QB's in his era are 2% or lower. You can debate that number all day as Bills fans do which I really don't disagree with. I mean Tua and Lawrence are a 2.2%. So what, like .2% worse? Why don't they get the label? I don't know. Maybe it's because they have never actually pushed Mahomes for the crown and Josh has so people had to find reasons to knock him down. Which I really do believe is the actual reason.
Josh does have a degree of control over this. His INT% keeps getting worse. Each year since 2020 which really should not happen. It's just reinforcing the narrative on him. I also know the only good QB in Josh's 2.4% area who is currently active is Stafford. Sure Josh has production like a pure animal and that does matter if you're sane, but purist and attack dogs will not allow a trade in INT% for production. They want to see the sub 2%.
Here is the active list for anybody that wants to look.
