I'm pretty skeptical the Jazz would do this, but I'm curious if there are any Celtics fans who wouldn't?
Celtics trade: Springer, Scheierman, 2027 #1, 2026 #2
Jazz trade: Kessler, Svi
My analysis is that I feel Kessler is worth a first round pick, at least, so a 1st and a 2nd is about right. Springer is the salary match. So I would do that part. I would try to send them Tillman for Svi over Scheierman. That is not so much about talent as it is maintaining roster balance. If we brought in Kessler, that would give us 6 bigs on the roster:
Porzingis, Horford, Kornet, Queta, Tillman + Kessler
Kessler probably beats out Kornet for the 3rd big, Kornet is still useful as the 4th big, Queta plays sometimes as the emergency big, Tillman would have no role. This would also work if you sent them Queta over Tillman. It is still a nice upgrade to get Kessler over Queta.
