Still wouldn't be as stupid as trading s bag, Green and $5M for DeRozan, Poeltl and the 29th pick (was always going to be 27-30).
I doubt even they'd do it as a last resort and I doubt even more so that the Spurs would have the balls to go through with it.
It's not like anything new was learned about DeRozan since the trade, so if they prioritized him over a package of picks less than a year ago, why would they trade him for a single one now? Especially when the likely pick would be a role player (the most valuable and scarce kind, but still).
