LOL... I've been saying it, but nobody believed it. I think that's what's going to happen.
I could be wrong, But I think the Spurs could package Diaw and Duncan's contract (assuming he's retiring), and get a player making around $13M - maybe someone like Allen Crabbe? The Blazers would get Diaw plus be able to spread Duncan's salary, so they clear about $4M, if I got that right. Or the same if they S&T Harkless for about $6m, and then trade for Tim's contract - they still clear up $4M by spreading. Maybe different teams/players, but they might be able to score a player by leveraging that $4m cap savings.
Other than that, I still don't see anyone the Spurs can afford who will be better than what they have, or the players who are in their pipeline - most of whom will likely get less than the guys they would acquire. As funny as it sounds after that KBP thread, I'm starting to count on the hope that Bourousis will be spending some time under the basket for the Spurs this season, and that Bertans will be back to 100% after the injuries.
