Sixers GM Tony DiLeo said that Andrew Bynum (knees) is entering the "most critical part" of his rehab when he returns to practice. "When he practices, bangs, jumps, moves - that's really the most critical part," DiLeo said. "We'll just have to see how he reacts during that phase." The Sixers have been in wait-and-see mode with Bynum all season, and there remains no timetable for Bynum to get back on the practice floor despite the big man saying he'd return around the All-Star break. Bynum is doing lateral movement and basketball drills, and for what it's worth, the big man thinks it will take around 10 days-two weeks once he starts practicing to be ready for a game. We're unlikely to see Bynum before the end of February, at the earliest. With Thaddeus Young (hamstring) out, Spencer Hawes is locked into a nice role right now.
