Draft Day assets Spurs can use in Trades

Ok looking at the roster with what we have and option's that where exercise and what the Spurs can use to leverage moving up the draft even a little. I don't see a way for the Spurs to get into the teens (unless Scola has more value than I think) but the early 20's I think is possible. Anyone have thoughts on who you think the Spurs will dangle as trade bait.

Guys that will not be trade on draft day (imo)
Duncan
Manu
Tony
Horry
Finley
Bowen

Possible but unlikely to be moved in trade
Elson
White

Guys the Spurs will look to leverage
Barry (1 year on his contract: would most likely be a player and pick swap)

Beno (who seems to have solid value he is a PG and had times he played well and teams are looking for PG)

Buttler a young Big man with little cost (be thrown in a packaged deal as an extra bonus type thing)

Scola who knows the guy has talent can come in and play day one having been in Europe this long still relatively young 26

I agree Beno, Butler and Barry seem to be the expendable ones. Of course if we trade Butler and Oberto and Bonner leave we could be left real thin up front. I would love for the Spurs to be able to get either Rudy Fernandez or Marco Bellineli.

Unfortunately I think the most likely trade is the Spurs trading away their first round pick. If the player they are looking at looks like he could be still on the board at 33 the Spurs may deal away that first rounder to save roster space and avoid a guaranteed contract.
