I generally agree with your sentiment, though I would limit #2 to the big four. You don't need to trade up to 2 if you want Lamar Jackson, for instance. There's a chance the Jets would take Mayfield, but I think they will pick Rosen. Mayfield is likely available at 6, but if you have decided he is the guy, take him at 2 if you want to eliminate risk of missing out.
