Let's f'ing hope! Because if he did, they could be a real, real problem for us in June the next few years. It's a bit of a staring contest between Wyc and the OKC, DEN, MIN and (eventually) SAS ownership. Or a game of chicken with their net worths.
Easier for a camel to pass through the eye of a needle than for a rich man to enter the kingdom of God annals of dynastic championship owners in the salary-cap era.
Anyway, I expect that Presti has the green light to make impact moves using his assets, but the right deal hasn't come along yet. Which makes IH a good fit for his waiting game. When the time comes, he has the big-contract asset he can include in a trade, he has the picks, and he has some cap room for the next ~24 months if he plays his cards right, which he usually does. They really need an impact center who can fit OKC's style of play, and IH was the best available version of that. (Or another two-way wing / 2-3 swingman to pair with J-Dub, who won't cost a max like Paul George). But when an Anthony Davis or Bam Adebayo or Sabonis (say) become available, I expect them to empty the clip.
Frankly, they really needed to be first in line for Porzingis last summer, could have overpaid Washington for the privilege (if they convinced KP of the project - which is what really sold him on Boston, of course), but the whole league was preoccupied with the draft and start of free agency and Brad, thankfully, stole a march on everyone. Or if they just hadn't made the Cason Wallace / Dereck Lively swap, since OKC held his rights originally post-draft - boy wouldn't that be scary, them having Lively on a rookie contract.
