Worst case, can't we just cut him and use the stretch position?
I would use Trice or the like as our last guard. Move Grant and Gallo as the primary PG's.

Wolves were wanting rid of Rubio's contract in the offseason. If they still suck this year, I think they may be willing to go for a salary dump of Rubio for Seraphin and Calderon. A classic IT trade! I haven't watched Rubio enough over the years- I know he's an awful shooter, injury prone and a good passer. If he was a top tier defender I would consider it, but I have no idea what his defense actually is like.
