Similar to what the Cavs and Clippers have done in Harden/Garland trade. Mavs get a better, younger player to help them make play-in/1st round exit which is where you wanna be with the new draft. Denver gets a older, but similar player on a shorter contract and saves about $10M. The pick is lottery protected and far in the future to where Dallas should be good by then. Val's contract is not guaranteed so that's another $10M and that should be enough to re-sign PWats (4 year $100M). And in free agency look for defence and rebounding.
