He's leading the league in turnovers, and passer rating is significantly worse this year. Completion % is what it was last year, but down from 2019. I do think he's a better passer, not sure if he's far better. I think it's circumstantial right now. Hope I'm right.
EDIT: I guess 3 years ago is his rookie year, technically, so yes he's definitely far better from that, even with this season's issues. But he's regressed in a big way from 2019 and 2020, but again, context.
He's making a bunch of mistakes lately, but I don't think those are reflective of his skills (or lack thereof) as a passer. His struggles aren't because he can't make the throws.
Overall, I think he's far more accurate now than he was in the past on short, middle, and long throws. The tools have improved, I guess. The usage of those tools is rather shaky lately.
