If the Celtics trade for Kawhi, I think it’d be for the Brown/Rozier/Morris/Filler package. Brown and Rozier gives the Spurs 2 young players to build around, which they need. Rozier is a significant upgrade over Dejounte Murray. Brown would be an incredible fit with Pop.I agree with Woj, Ball is just not a Spurs player. Pop would probably quit rather than deal with that circus. Dealing Kyrie means Rozier, who can't pass, is your PG. It's basically a no distributor but lots of length lineup. I'd rather keep Kyrie.
The Celtics would then have their superteam of:
Horford
Tatum
Kawhi
Hayward
Kyrie
With bench of:
Smart (assuming be
Theis
MLE
#27
Ring chasers
Owners would have to be ready to spend some serious money to make it work more than 1 year, and Kawhi/Kyrie would have to want to stay, but that lineup would be unstoppable.
