Giannis going to Portland to be reunited with Dame/Jrue would be the funniest ending to the Portland/Bucks loop that started with the Dame trade. This trade would create a rather potent team as well next season with Dame/Jrue/Deni/Giannis/Clingan and Sharpe/Camara/Yang off the bench. All while the Bucks continue having to pay for Dame's salary.
OKC is only involved to smooth over the draft compensation, and I don't really do trades that don't involve OKC...
