It goes through BA because that's the formal path to the FIBA. Unics shouldn't be approaching a contracted player, and judging from the comments, I'm guessing recruiting isn't supposed to take place at International tournaments? They seem to have a problem with him being approached there, and indicating that that's not allowed. I'm not sure.
CJ is staying with the Kings this season. The Kings have said that with a week to go till seasons tip off, he can't be released. The compromise is, CJ will be released out of the last 2 years of his contract come the next off season, should he get another offer. Looking at it from the position of both parties, that's a pretty fair deal. If it were a month ago, I'd say they would have let CJ walk.
