The Los Angeles Lakers sit atop the Pacific Division and have won seven in a row, but things haven't been easy lately for the defending champions. In the course of a week, Los Angeles has eked by the Detroit Pistons in double overtime, needed overtime (twice) to beat Oklahoma City and then fell behind by 20 to Memphis on Friday night before rallying to win by 10. The Lakers cannot afford to do that when they play at the Denver Nuggets on Sunday night.
