It’s going to be KAT. Just look at how they interact. It’s not personal, but from a game standpoint they freeze KAT out on offense, complain about his defense, and they are all have ties to Brunson.
The problem with KAT is I don’t know if they’ll get good value for him. This would be another team trading him in back-to-back off-seasons. They would probably have to take back a bad or questionable contract.
The only exception I could see is maybe the Suns would take him in a trade for KD given KD’s age, one year remaining on his contract and KAT’s relationship with Booker.
