I'm doubtful that anybody that Chris Wallace relies upon for advice would be spilling his guts to a Grizzlies message board. Anyway, when I followed the link, I didn't see the cited post, so it may have been deleted.
As for whether or not Antoine gets bought out, I think the biggest consideration is whether Memphis wants to use his contract either this year or next off-season (since he has a team option) to try to bring in an impact player. If they do, they'll keep him. If they don't, I'm sure they'll buy him out. I don't think how Antoine plays in Memphis will affect their decision one way or the other.
