I don't want JR Smith, but he is only due $14.7 for next year and that's it because 2019-20 is non-guaranteed.
I bet the Cavs do this deal in a heartbeat after the Hill trade:
Favors and Hood for JR Smith, Osman and the Brooklyn pick.

In all likelihood, the trade saves Cleveland money this year and next year. Hood is better than JR Smith and Favors can be very helpful for their post. In two trades, they would have added a PG/SG, a SG/SF and a PF/C who all help their matchups against Golden State. They aren't going to be able to find any other deal where they dump JR and add two useful players.
