Kawhi could be damaged goods. Has one year left on his contract and isn't signing an extension till he is a FA.Kawhi Leonard is one of the best players in the league. Jayson Tatum is coming off a very good rookie season. I think he's going to be awesome. He may also never be as good as Kawhi.
Like I said, I understand Boston is very unlikely to move him. But I don't think asking for Tatum is such a non starter that it would scuttle negotiations. It's not like Pop is offering you Danny Green.
Tatum has 3 more years of control.
It is a nonstarter.
