So they'd fall in love with a player enough to give up a first-round pick, but not enough to have used their own second-round pick on him? I would find that really unlikely.
That kind of thing might happen if we had a mid to high second-round pick and the other team had a low one. The other way around, I don't see any way you're going to get a first-rounder for a pick at the end of R2.
And besides, I don't think this draft has ANY quarterbacks worth breaking your neck for like that.
I mean, yeah, you kind of acknowledged how unlikely all this is, but even the unlikely chance seems like it has issues that would prevent it.
If we're going to make a move for a QB in the next few years, it's probably going to be that year's first plus the next year's. More likely we just do this with Ben's retirement and the simultaneous salary cap shitstorm:
... then use the next season's 8th pick or whatever to get a QB that is hopefully good.
