Luke Kornet has been the best big not named Porzingis or Horford so why would he not keep playing him? Queta appears as though he could challenge Kornet for those minutes, but he has not beaten him out at this point.
Has he? I think Queta is better and has a real chance to be A LOT better given minutes.
Has he what? Been the best big other than Porzingis and Horford? Absolutely. Queta has been decent too, and may well have more ceiling, but he is 24, not 20 or something. Being "raw" still at 24 means you are starting to put some limits on your ceiling.
The main question was whether or not Kornet should play. I think they both should play. But Kornet is going to be better than Queta as a fill in starter, as demonstrated by the TOR game. What he lacks in raw physical athletic ability relative to Queta, he makes up for with basketball IQ or whatever you want to call it.
I feel like Kornet is a great value at $2.4M for the role they ask of him. He can step in and start and help the team win. And then go back to the bench for several games without getting a bad attitude. That is valuable. Queta is also a great value as a 2-way. To be able to plug him in as a bench big and have him actually help the team, puts him in the upper 95th percentile of all 2-way players. That is great, extremely valuable in its own right. But he is raw, and raw is hard to have play with the starters.
