The Celtics are in the driver's seat with 3 all star max guys starting alongside two budding all star talents still on rookie deals. 5 all star talents in the starting 5. One shouldn't tinker with that. Really, it would take an Anthony Davis (replacing Horford) to improve that 5.
The bench looks pretty good if we can bring Monroe back. He's showing to fit well and be a 20/10 threat off the bench, and his passing is fantastic. And Rozier, who I'm high on, could drop 20, and Morris as well, and I like our 1-8 for a title run next year, with or without Smart.
Kawhi seems not worth the risk. We've got a good thing going.
