Both teams should stay clear of such a trade. A KG for Randolph trade doesn't make the Grizzlies better, I'm pretty sure you realize that despite your post. Randolph is 30 he has no future with a rebuilding team. I think trying to get Gay from Memphis would be a better idea although I absolutely hate his contract.

If you want to throw a quick young play-off team together trade KG, filler and pick(s) to Memphis for Gay. Memphis does it as a pure salary dump might be able to squeeze out Mayo if you play your cards right and they really want out of Gay's contract. Then flip Ray and a filler to Atlanta for Josh Smith. Atlanta does it purely as a salary dump and to get rid of a malcontent. That leaves us with Rondo, Mayo, Gay, Smith, O'neal and Pierce off the bench. We lose cap room and probably picks, but it keeps us out the lotto and I like that team more than our current 1. The bad news Rondo, Mayo, and Smith have all had questions surrounding their character.

what is with the ridiculous pipe dreams?

Why would a reasonably young team like Memphis make a trade that will leave them with nothing next season? Especially since Randolph for KG is probably a major downgrade come playoff time when Randolph will presumably be good to go and KG will be worn out.

They are essentially giving up a 1st rounder for the privilege of being worse this season and way worse next.

Do trade ideas like this come from an inability to see through the eyes of other teams?

Mayo, Conley and 1st rounder for Rondo...

Blow up the rest of the team as well.  Build around cap space, young prospects and draft picks

Ugh. No way. That's a brutal deal for Boston.
