I'd be surprised if the Sixers would consider trading a big since Bynum has been a no-show so far this season. But if Collins does cut lose a big, I'd go after Moultrie or Hawes. Brown has been the league for 11 years and has been a bust on every team he's been on. One of the biggest draft busts in league history I believe. The only item I'd give for Brown in a trade would be one of Pop's fine wines and that would be an empty bottle at that.
Light travels faster than sound; this is why some people appear bright until they speak.
