He gave the the gm of the team, whoever it was, the power to make trade for the team. He makes a trade, a pretty decent one, and then Stern goes back on what he says. It [expletive]ed up the chemistry for Houston and the Lakers. It was unethical.
It was Demps. Do you have a source that definitively states that Demps had, without further consultation with/ approval by the owner, the unfettered ability and power to conduct any trade he wanted? If he had that power, that is news to me, and would far exceed the power of any other GM in the league.
I think the more likely scenario is that Demps was give the instruction to seek a trade for CP3 and get the best package he could, with a preference for young players and picks, and then bring the proposed deal to the owner. He did that. The owner didnt like the deal because it involved older players and higher salaries. The owner instructed Demps to look for a better deal involving young players and picks. He looked and he found one, which the owner then approved.
