Not sure how you put OKC in that equation they would have to make it to the Finals as the number 8 seed I don't think that's ever happened before...
Everything else come's down to seeding who plays who in the Playoff's impossible to predict as of right now. But with the way things are shaking up Bull's and Cav's could play each other in the 2nd round which would be hilarious.
If I had to guess I would say
Memphis and Raptors
If the Cav's beat the Raptors with Demar in the Line up then Cav's will make it to the Finals.
