Nice game, but a lot of good players have breakout games (and Kuzma is a good player).
As it pertains to the Celtics - I don't think it really moves the needle. As an older, later pick, Kuzma probably still holds about the same value as Ingram/Ball and maybe Brown. Tatum still blows all of those players out of the water with his age, pedigree, and production on a winning team.
I see Kuzma as closer in value to younger Marcus Morris than Jayson Tatum.
