The Spurs have always been pretty conservative in terms of trading away draft picks, and now that not only the long-term, but also short-term future is a question mark, I can't imagine they'll be too free-willing in regards to trades that involve shipping out their picks. At most, I see them attaching a second as a way to sweeten some kind of deal, perhaps something like Gay and a second for whatever prospect at the deadline.
In terms of the vet-younging balance, tbh, I think they've done a pretty solid job this season. Everyone's freaking out over the GSW loss (not that I'm happy myself), but it's still a learning experience for the young players, and exactly the way most of us saw this season going: the team won't be good enough to make the PO's, we'll get a late lottery pick, and get rid of some bad contracts in the off-season. Whatever we do with that cap space, I don't know, but I'd say things are going quite well so far. If only the core played more consistently...
The only hope for next season is that the cap space isn't wasted on more useless vets. There's good vets, and bad vets, and our team is full of the latter, IMO. We should be able with that money to command older players that can both be teachers to our young players, and also actually contribute to good team ball and wins, instead of calling their own shot every time they're on the floor, á la Chucky Mills.
