I like the idea of getting both Jerami and Thybulle. If the Kings FO can pull this off, the team will be very well balanced. At least on paper and only needing a backup Center. Jerami adds a 2nd player with some 1-on-1 iso ability to the starting 5, which the Kings only currently have when Fox and Monk are playing and they're too small as a duo. Thybulle can be the POA defender. I would even be fine with keeping Barnes in that event, as he will be relegated to the bench.
1-5: Fox, Thybulle, Murray, Jerami, Sabonis
5-10: +Davion? +Monk? +Barnes? +Lyles? +Who?

The Kings FO could try getting Goga Bitadze for the backup Center role? He's 3rd choice Center with the Magic and not getting guaranteed minutes, so being bumped up to 2nd choice might attract him to playing for the Kings instead.
Another potential option for that backup Center role is Karlo Matkovic? The Pelicans have his draft rights. I have not seen him play in games. His highlights look impressive enough though. Seems like he plays similar to Isaiah Hartenstein. A 7-footer who brings energy, rolls hard, protects the rim and rebounds as he has some bounce, can shoot the three a little. The Kings FO should at least give him a look to see if there's anything there.
If his name was Karl Collins instead of Karlo Matkovic, would you rather have Karl or John Collins on the squad? I think I'd prefer brother Karl to brother John.
