From a pure basketball perspective I'm really excited about this match-up. Great post-offense vs. great post-defense and awesome perimeter-defense vs. awesome perimeter-offense.
So, like always, it comes down to match-ups. Perk should be able to contain Gasol to some extend. But I can't see Ibaka handling Z-Bo at all. He's just too [dang] big for him, so Ibaka will have to do something with his athleticism. I have no idea how Battier plays against Durant but I know TA can really frustrate him. Problem is, Conley has no chance of defending Westbrook, so it could be TA has to guard him.
While I can see all of the above match-ups somehow even themselves out, I think 2 things will more or less decide the winner. First is: Who will have the bigger impact between Mayo and Harden? The second is late game execution.
But no matter how things turn out, I'm pretty sure it will be awesome.
