Well, hcsilla, I have to admit -- even though no one here likes your trade proposal, we can't seem to agree on which side it's better for. So maybe it isn't quite so bad after all.
I think it would be a pretty good trade for Phoenix. They save some money, even though it's not as much as you're saying, since you're forgetting that the Suns would have to include cash in order to offset Gugliotta's trade kicker. But they save some. They get a player who might be a contributor in exchange for someone who clearly won't be.
I completely disagree that Denver would have any interest in this trade. Taking on Gugliotta's contract right now would seriously hamper them in this summer's free agent market. You have outlined one extremely complicated scenario, involving (by your count) six assumptions. In many other scenarios, Denver just gets screwed. They have worked hard to have their salary flexibility now, and I don't think they would give it up just in order to have some of it later.
In my opinon, there are two other things you are overlooking:
1. Gugliotta reportedly has a "gentleman's agreement" with Colangelo that he won't be traded. If there were a proposed trade that helped the Suns a lot, I can imagine that this agreement might be broken. But your trade helps the Suns only a little. Colangelo (assuming the reports are correct) will probably keep his word.
2. Gugliotta might not take his option. It would be just as easy for everyone involved if Gugliotta declines his option, then immediately signs a two-year contract that exactly matches Camby's. He gets more total money, while the Suns get the same savings (actually more, since they don't have to pay for Gugliotta's trade kicker), keep their draft pick, and don't disrupt their chemistry or reputation.
