Andrew Bynum wants to make his season debut three weeks from now. “That’s just me,” he said after a rigorous on-court workout this afternoon at the Lakers’ training facility in El Segundo. “The training staff and other people may see things differently. I don’t have a target. I just want to be back within three weeks. That’s my personal goal.” FYI: the Lakers play the Raptors in Toronto on Dec. 19, three weeks from Sunday.
