I thought we were going in a Sully/Zeller debate direction, in which case they play different positions. Sully can be better than Zeller, while Zeller still starts.
I mean, I guess.
It becomes a matter of how to approach filling the starting 4 spot next to Zeller, which is where we get two POV's.
Sully is better, but KO presents a nice look next to Zeller, who we established is starting 5.
I'd try to "go big" before I'd try anything else, and go with KO at the 4, and Green at the 3 for a big/long front line.
Turner at SG adds to the length on the court even more.
But as Celtics, we can accept that a better player might come off the bench for the good of the team, balance, chemistry, and winning, and be 6th man. The 6th man is supposed to be a starter-level talent anyway, so it's no demotion.
And they make a nice, young and improving, and very talented 3-big rotation.
