My second to last 2018 NFL Mock Draft with 49ers mock

I'm not a Giants or Jets fan obviously, but it would be cool if Darnold and Rosen remained cross town rivals.

If Mayfield is there when we pick, I would be looking to trade down with the Bills, because Miami might take him. Wonder what extra we could get from them for moving down 3 spots? The value chart says the difference is 150 points, but with QB's it normally means we could get a tad more value for it. Perhaps we could get the 12th pick plus the 65th pick for the 9th pick plus the 128th pick in the draft? We'd gain just over 100 points in the trade, but they'd get their QB. Then at 12 we could pick R. Smith, and then be able to add more talent to the team with the 65th pick. Basically move down 3 spots in the 1st, and trade away a late 4th for an early 3rd. I like it.
