Well, if he's bought out isn't the contract dissolved? In order to play, he would have to sign a new one
No, because it applies to contract he was amnestied from. The contract the Rockets gave Luis was up to 2014/2015 season, thus he is not eligible to return to the Rockets until 2015/2016 season.
Didn't we amnesty Scola? If so, he can't be resigned until later. Maybe someone in this thread knows for sure.
IIRC, he is still under the same contract he had when he was amnestied, if this is true then he can not come back to the Rockets until his contract expires.
The waiving team may not re-sign or re-acquire the player for the length of his contract (which includes seasons following an ETO or option), and the claiming team is prohibited from trading the player until the following July 1. If the player is eventually traded, his new team becomes the claiming team. . . . . 2 A protected year is one in which any of the salary is guaranteed. Seasons following ETOs and player options are considered to be protected years, but not seasons following team options (see question number 58). The minimum bid does not include salary in seasons that are completely non-guaranteed, however the team with the winning bid is responsible for paying this salary. Interestingly, the CBA does not specify the minimum bid amount when the entire remaining contract is non-guaranteed, although there is no reason for such a contract to be amnestied. http://www.cbafaq.com/salarycap.htm#Q68
