I did NOT see this coming... Wow.
OKC is my second favourite team, but I don't know if this makes them better in the short-term. It may in fact, as Westbrook may respond positively to Harden being gone.
Presti doesn't usually make mistakes, so maybe Martin's outside shooting will work better than Harden's driving. The Thunder also get some young talent coming back and some picks, maybe that will help keep them competitive for a long time.
