Right now Kuz is in a similar role to the one AG had in Orlando where he’s being asked to do too much offensively.
Gordan is more athletic and a slightly better defender whereas Kuzma is better as a shot creator, but I’d say overall they have a similar “jack of all trades master of none” skillset.
Kuz is not a starter on a title contender. However, He can be and has been a quality 6th man/spot starter on championship team.
