3 things I would not give them: the Lakers pick, Tatum or Brown.
If Boston has to take Thomas back and he is going to miss most of the season, it really makes it tough in them. Larkin is a scrap heap PG and rozier is not an NBA starter. You have no legit PG.
Thomas' value to this team is zero if he cannot play. Nobody wants him in a trade. He cannot play and help the season. Just waiting for him to be a FA so he can go elsewhere.
