I was saying their talent level isn’t debatable, which it isn’t (as you said). I think you’re looking too much into completion percentage when it comes to accuracy. Stafford is a lot more accurate than Dak. To me, that isn’t debatable. Dak has come a long way with his accuracy, but he’s not Stafford in that regard.
As for Kupp, of course he was on the verge of breaking out. But there’s breaking out, and putting up the best single season that any wr has ever put up. Stafford elevating Kupp’s game has been the difference this year. At least in my opinion. Dak doesn’t do that. I’m not saying he can’t, but in my opinion he hasn’t. That might be on Kellen/Linehan as much as anything since Dak doesn’t have mcvay, but I think there’s a noticeable gap in their play. The thing I always held in high regard for Dak was his borderline irrational confidence, and his leadership qualities, but I feel like even that dipped this year with the blaming the refs bullshit that this team did all year.
