But lets not get carried away. He obviously has huge offensive potential, but as others has mentioned currently employs his skills in a rather inefficient way. If you don't like box score measures like RPM or win shares, per 82games the Knicks offense was slightly better with him off the court last year. Having said that I definitely agree that he's being held back by the dysfunction of the team..
RPM is an on/off stat, though heavily modified.
BPM is a box score stat. KP's bpm this year was 0.2, about halfway between Smart (-0.3) and Olynyk (0.7)
If you're a WS/48 person, KP was .1, about the same as Tyler Zeller (.094)
If you're a VORP person, he was 1.2, a little better than Smart (1.0)
You can argue with all of the advanced stats. They all have some holes. But, this is not a star player right now.
Jimmy Butler, by comparison, bpm 6.9, WS/48 .236, VORP 6.3.
Of course you can say box score stats over favor wings (my retort would be they merely demonstrate how important wings are to your team, but horses for courses). They certainly favor usage which is the most important consideration when looking at them. I suppose as a 2nd year guy on a team with Carmelo we can imagine why KP wouldn't get as much usage, but these numbers still kind of lag. Here are some star big men:
Anthony Davis: 3.7, .195, 3.9
Rudy Gobert: 5.8, .250, 5.4
Plenty of reason for everyone to be excited about Porzingis. And sure maybe you fit him into Stevens system and he's amazeballs right away. But I think people are getting carried away with his actual production on the court so far.
Anyway, with Jackson apparently fired, I can't imagine Porzingis won't be a Knick for at the least the near future.
