There's really no evidence that it would cost that much so it's kind of a silly question to ask.
I have conviction that he's a franchise quarterback that will be one of the most threatening signal callers in the NFL for however long he plays, which I assume will be an average length of time.
What is that worth to you?
It's worth to me whatever the market will bear. There is such a thing as him just being out of reach. If Arizona or Oakland are trying to tell you they covet him, yet they're offering to trade you the pick, I'd call their bluff. I'd make them prove it by trying to go deep into negotiations for Josh Rosen or Derek Carr, and if they're not willing to part with them, then you know they're bluffing.
But if another team is after the pick and they're offering what you say then yes, ultimately I'll pay the price the market bears.
This is QB1 in this draft, and an absolutely unique prospect. You can't really say that every year. You tried to compare this to what I said about Weeden but that's really a very poor comparison since Andrew Luck was my QB1 in that draft and had been for literally 2.5 years.
