You'd have the same problem with Trent in the short term as well.
If Trent Richardson were to fall to #10 the best scenario I could think of would be multiple teams, including Cleveland who has picks 22 and 37, wanting to move up to get him. This could also be the case if Tannehill were to be available at pick #10.
I also don't think a package of Spiller and a 3rd get you a 1st, even a late one.
