You keep saying this, but it only exists in your imagination, particularly the part about what the Spurs are getting back. The only announcement has been that the Spurs traded Tiago Splitter. There has not been a single shred of paper filed with the league office, because it can't happen at the moment. This is not the same as the Gasol trade, which took place in the middle of the season. This is an announcement during a mandatory league moratorium. If you can come up with a rule that it violates, either spirit or letter, I'd love to see it.
