Dallas should 100% tank, next draft is the last one they control in a while and they should aim at pairing Flagg with another top prospect from a good class , keep youngish vets unless they receive a great offer (PJ Washington, Gafford) and sell the rest for what they can (Anthony Davis, Kyrie). Say they get a top 4 pick, pretty much any of them are good fits with Flagg and you'd have a great young core plus Lively, Gafford, PJ Washington, and assets to go from there. With that said, I hope they keep themselves in play-in territory and have no shot at a top pick, we don't need any more competition in the West.
