He's not going to stay in Toronto, it's a Hockey town. There will be no 175 million dollar sneaker deals in Toronto. The Raptors wanted to get out of the DeRosen contract and they did. Just like they want out of the Ibaka contract. They're paying an aging Lowery 31 million a year...I'm sure they want out of that contract too.
IMO in the long run, what they really want is to rebuild asap.
Kawhi will end up in LA by this time next year, by trade or FA.
In the meantime, Toronto will be a good team. The C's will be just as good if not better.
