If Ron gets traded and bought out, he will most likely re-sign with the Lakers. He is a known KG hater. I remember reading an article by Peter Vescy after game 4 of the 08 Finals. Peter sat next to Ron. During the first half Ron was clowning KG basically asking why KG was not being his usual loud, intense, trash talking self. After the game Ronny was sad because the C's cameback.
Ron has always wanted to play for the Lakers. There was also a story about how after the Lakers were defeated in 08, Kobe was all alone in the showers washing away his tears. Supposedly, Ron walked in the Lakers locker room and told Kobe that he wanted to play for them.
If the Lakers make any kind of trade and one of their former players get bought out, I think they would re-sign with the Lakers.
