His value would have been highest on draft day, yes, but the ownership was committed to him. Some speculate Hink Dogg wanted Dat Zingis and the ownership overruled him. If that were the case--they didn't even want the very next player taken--they certainly were not open to trading down/out either.

If some of the reports flying around now are true, his trade value is every bit as high as it was during the offseason if not higher given the lack of available pieces on the market.
