It wouldn't happen in Philly for a few reasons....
1. The Sixers don't have enough money available.
2. He isn't well liked in Philly by any stretch of the imagination.
3. He would take the backseat to Iverson because Allen is the most popular athlete in the city period not even an arguement.
I like Memphis as a destination, I wouldn't rule Chicago out either. I don't like the Boston fit because of Paul Pierce being there and Ainge has apparently decided to do what the Sixers do with Iverson and surround him with absolutely nothing.
