After this trade,

For Mavs, they will get Fox who is only 28. I know he didn't show up consistently in the playoffs for the Spurs, and his subpar production was a big factor in the finals loss. It's very easy to forget that he was nursing an ankle injury throughout a good chunk of the postseason. Fox will be a perfect mentor for Flagg & MJJ. They can be a long-term cores. BTW, Mavs have to insured for salary space after three years. They can get rid of Kyle and don't worry about paying a lot of money for his extension after two years.

For Spurs, Kyle's contract is only two years left. They will have salary space for Wemby's max contract. Extend Klye? They will not need it.

Who say no?
