Philly's not a title contender, and it's actually a benefit for Boston if Philly is better next year than it was this year, in the sense that it likely gives the 2017 Brooklyn pick a better chance to be higher than the Philly pick. You make the deal if you like Okafor better than what you'd have available at #3, because you need much better play from your bigs, and Okafor should provide that. This isn't rocket science, and people are over thinking it.
