Should we sign Luka Garza too (again, younger)?
There is no rush to sign him to an NBA contract. Doing so would require releasing someone, eating the contract. If later there is a trade that requires us taking on more players than go out, we would have to again release someone. That's a lot of waste when we have full control of his rights with his two way contract and could easily convert it after the trade deadline.
Even then, do not forget that we have likely two lottery picks (would call the GS pick late lottery to mid first) that we will need roster spots for next year.
