Its pick 27.
Wildly best case: He becomes a cornerstone defensive big in the mold of De'Andre, Cappella.
Worst Case: Third big off the bench good for a couple dunks, a block and six fouls.
Most likely scenario: Decent bench rotation player, good for a solid 15 minutes a night.
If you expect anything different out of a 27 pick, I don't know what else to tell you. He adds to the length of the team, and if can use that length and athleticism effectively for 15 to 20 minutes a night, this is a home run. And if he never gets it, he doesn't cost much and he'll be trade filler or not re-signed at the end of his rookie deal.
