I think that KO for Noels would be good for both teams. We desperately need the interior defense, and they would get a great perimeter stretch 4 to put next to Embiid when he is playing. I think that KO/Embiid would be a better frontcourt than Noels/Embiid because the defense would be great but on offense the paint would be crowded. Embiid would mitigate the defensive woes of KO, and the offense would flow much better.
Sully and Noels would be a strong interior, and with Zeller off the bench, we would have a good front court defensively, though perhaps crowded. If Sully's 3 pt shoot ends up in the 33% range like I think it will by the end of the year (I think he is much better than his current clip) it would allow a lot of room on the offensive end. And Noels/Zeller frontcourt would give use a combination of Zeller's nice footwork and finesse/passing around the basket, with Noels athleticism and ability to finish around the basket, especially with Rondo pounding the ball on the inside.
So to sum up:
Sully for Noels... not my wheelhouse.
KO for Noels... Yay!
Will it happen?
NOPE!!
