Wizards play at the 2nd-highest pace in the league and have the 2nd-worse defense in the league. It's easy to put up numbers when you play fast, don't play defense, and are usually so far behind that your opponent isn't even trying.
Wizards are a (checks the numbers) -13.7 when Kuzma is on the court this year, and a +1.2 when Kuzma is on the bench. Doesn't mean that much with such a shytty team, but his stats on such a shytty team don't mean that much either. We already know what kind of player he is and the problems he presents contributing to a decent team. Gonna take more than padding stat on a bottom dweller to change my mind.
