Some playoff caliber team (Denver maybe?) will do what Toronto did and acquire Davis with the hopes being they can sell him on sticking around long-term.
There’s no real reason not too. Even in the worst case scenario that Davis leaves you high and dry after next season, you still maximized your chance to win an NBA title this year if you get him now and next year in 19-20.
Beyond that, as we saw with the Leonard deal, when these guys publicly make trade demands, it usually destroys the leverage the team left holding the bag has anyway. So a team looking to acquire Davis will very likely be able to get it done for less assets than people would expect.
