Let me start by saying I have no source to support this whatsoever, it came totally from my brain.
That said, I think Boston could be a potential landing spot for Iggy. The Celts are (according to yahoo, http://sports.yahoo.com/nba/rumors/post/Celtics-dealing-Ray-Allen-?urn=nba,217085#comments) considering dealing Ray Allen and his $20 million EC. According to the link, they want a younger guard (Iggy) and an another EC(likely Kapono).
This really gets us nothing but money. I be would totally against this ever happening because Iggy should never be involved in a straight salary dump, but my guess is that if the Sixers get desperate, they might play around with this idea.
