If you want to see OKC in Golden State's side of the bracket, you should be rooting for Portland. If Portland wins, OKC is 4 or 5. If Utah wins, OKC is in the 6.
So there's no doubt in my mind that Portland wins. Because of course, the year the Warriors kind of, maybe look a little vulnerable, they'd end up on the same side of the bracket as a DOA Spurs team, a Pelicans team missing Boogie, and a Portland team that's just kind of... eh.
Meanwhile, Houston would have to deal with Butler-Towns, then either Utah or OKC.
