I get that odds are slim for Rubio to pass but with a new a child at home, his first child, I think there is a greater chance than normal he passes. It is the Olympics though, which is treated much more serious than the usual FIBA tournaments so odds are slim of him passing.
Baynes playing or not playing isn't as much of an issue since we don't need to resign him. If he wants to play in the Olympics, that should be another reason to pass on resigning him. If he's willing to sign for around $3-4 million, or less, then I'm not against bringing him back but he shouldn't be the primary backup, unless the 3rd big is a rookie big that they plan on covering for Baynes for half the year.
