Spurs, if my math is correct, have a path to having some cap space. Basically, it would be letting go of all players that are going to be FA (including Rudy), picking up all the options (White, Murray & Jakob) and then trading Mills with no salary back.
If they did that, they would have about 15M in cap space I believe. Losing Mills shouldn’t be an issue with Lonnie/Murray in the fold and they would have 15M (in addition to being able to keep their 2 first round picks on the books) to replace Rudy.
So it would be this years team less Mills & Rudy, but adding Lonnie, Murray, 2 first round picks and a player for 15M APY.
