I hear y'all on this likely being some fake leak rumor, but just for fun (only this is no fun at all), here's the draft chart:

So using these numbers, our 1st and 2nd round pick would equal between the 7/8 pick, which is probably right around where "trading into the top 10" would be.
I'd be annoyed enough if we spent our #15 overall pick on Christian McCaffrey. Blowing our 2nd round pick in order to do it? I mean, there's no way, right?
