Plus, if you actually do the math, Spurs won't have enough space for a max contract if they renounce Manu, Mills, Pau, DD, Lee. Trade DG. Then draft/stash pick, trade Kyle, trade Forbes. Still not enough. They have to trade another 10+ mil/year guy ( TP or LA). Trade LA and you get to keep pick, keep Kyle, keep Forbes/Bertans and have close to 50 mil in space.
With Pau declining option.
SA renouncing Manu, Pau, Mills, Dedmon, Lee.
SA trading DG.
Simmons cap hold at 1.67 mil
Spurs should be at 29,376,682 in space.
After that SA has options: If SA trades Kyle -- that's just creates 1.5 mil in space. Bringing us at 30.8 million. Then draft and stash the 29th -- that adds another 600K in space, which brings us at 31.4 million in space. Trading Forbes -- only saves around 100K (same w/ Bertans), which brings us at 31.5 million in space ( still not enough for CP3 Max).
However if SA trades LA and gets back a top 20 pick ( 2-4 million cap hold) that should create another 17-19 million in space, bringing SA to 46-49 million in space. Enough to sign CP3, re-sign Pau then SA can go over cap to re-sign or match Simmons -- all while keeping the pick, Anderson, Forbes/Bertans. Spurs can re-sign Manu and Lee to the minimum after all dust settles too.
