If he keeps his shooting efficiency up and we end up overtaking the Cavs for the 1st seed, he'd have a case.
It's unlikely that anyone on the Warriors win. If the Celtics have a better record than the Cavs, then you could make the case for IT instead of Bron.
Then it's just Harden, Westbrook, or IT. Unfortunately, with the historic offensive season we are seeing so far, it's unlikely that IT overtakes either of them.
