This scenario assumes two things that are mildly likely.
1. Minnesota does not pick a PG with #6.
2. A PG (Jennings, Flynn, etc.) that Minnesota wants slips to us.
We trade #13 & #52
We get #18, #28, #45.
It's pretty well known that we'd like another draft pick. I could see us doing this and then picking guys like T-Will or Sam Young and Jeff Pendergraph or Gani Lawal. That would give us a pretty nice draft. We'd also move up 7 spots in the 2nd round, where we just might snag someone who's worth a roster slot.
