I don't recall if I have every seen him play. I think we can hope he ends up like a Duncan Robinson or Sam Hauser. Here is where I see him fitting in nicely:
Holiday Pritchard Springer
White Hauser-TO Scheierman
Brown [ Vet? ] Walsh
Tatum [ Tillman? ] Queta-TO
Porzingis Horford [ Kornet? ]
That is not a terrible 3rd unit. He would fit right in to that Mykhailiuk slot, but hopefully with more upside. If we do take a player in the 2nd round, I see that player as a 2-way, so may as well go for a high ceiling type.
I do feel we need a legit reliable vet for that second unit wing/swing role, doesn't seem we have someone for that role right now. Then I wonder if we keep all 3 of Tillman, Kornet, and Queta. I would prioritize Tillman as he fits that PF role better. Kornet is better than Queta but may cost more $$$. Knowing that Porzingis will miss games, Kornet has some value.
