I'm really not getting what you mean by this.
If he gets a first round grade, he goes. If he gets a first round grade and slips to the second round, he's still gone. If he gets a second round grade (which is highly unlikely, as I've said), I still think he goes.
This has somehow turned into "Katz thinks Carr is a second rounder." That's not at all what I said above, or anything close to it. Hypothetically speaking, I don't think there's a world where Carr comes back unless he gets a 4th - 7th round grade, which is never happening. Hence, I think there's not a chance he's back next year.
I'm confused how this has somehow turned into me not thinking Carr is a good QB, nor that he's unworthy of a first round pick 😂 And in effect, you're making my argument for me - lots of ass QBs go in the first round; Carr is better than those guys; so Carr jumps to the NFL, most likely knowing he goes first round.
