Chicago and Philadelphia are two under-the-radar teams sources suspect will become more aggressive on the day before the deadline. The Bulls and 76ers have started being more active just this past week. It’s also been reported the Bulls have a standing offer from Toronto for Carlos Boozer and John Lucas III. Andrea Bargnani is said to be the centerpiece from the Raptors’ end. The Raptors have also engaged the Sixers in conversations centered on Bargnani, sources said. No word on what the Sixers would need to offer in return, although a Western Conference executive suspects it would involve center Spencer Hawes.
