I'm no expert, but I respectfully disagree. I am afraid the Sixers are cruising on one of the three easiest schedules (to date), and that they will not make the playoffs. But I am wrong all the time!
After last night's impressive performance against the Bulls, I think that it's safe to say that the Sixers are indeed for real. While it's true that they don't have any real "stars," they make up for that deficiency with strong, unselfish team basketball. Combine that with the outstanding coaching of Doug Collins and you have the makings of something great.
A Dwight Howard trade is an interesting proposition. There's no question that he'd make the Sixers better, however, would it be worth the enormous acquisition cost? At minimum, the Magic would probably want Holiday and Turner, and perhaps Iguodala. Who replaces those guys? Moreover, would they want to disrupt a team that obviously has tremendous chemistry? And even if they do get Howard, there's no guarantee that he re-signs with the Sixers. If he walks, then they'll have traded several valuable assets and walked away with nothing. I don't know if I'd be comfortable with taking that kind of risk.
If I'm Rod Thorn, I see how far I can get with this group this year. Then in the offseason, IF Howard is an FA, I make a strong play for him.
