I think a lot of the trade ideas on here simply build on reports from the media. For instance, if Phoenix is considering trading Amare and JRich for Jermaine O'Neal, why not see if we can swing the same thing? If Iggy is available to a team taking on Dalembert's salary, why should we explore it?
A lot of times, the original media report is wrong, but I think it's fair for members to speculate and come up with ideas.
There are definitely some off the wall ideas in here, but I think overall, people can at least justify their thinking.
