Andrew Bynum is acutely aware how many Lakers fans spent the offseason coveting Dwight Howard. Judging by his first three games of the season, Bynum seems determined to prove to every basketball fan in Los Angeles that this team already has a star center. Kobe Bryant scored 37 points, Bynum had 21 points and 22 rebounds in the first 20-20 game of his career, and the Lakers beat the Houston Rockets 108-99 Tuesday night for their fourth victory in five games.
