sixers will be improved no doubt, but still, far from contending. i see them being 5 at best in the east. boston is still 1, detroit/orlando (getting pietrus was a huge steal, he will flourish in orlando)/cleveland will make some mess for 2-4, then toronto, philly, atlanta (if they keep josh smith), jersey, chicago if they can properly sort out their roster and maximize the value (hinrich in golden state? could work!) round out your playoff contenders in the east.
as far as my beloved warriors, gugu said it best, they are moving horizontally; getting brand would have been huge, and im sure baron davis wishes he had a time machine now haha. but this is a young team, maggette will do quite fine in oaktown, and they had to overpay to get him, and needed to get someone to avoid the offseason from being a total loss.
