Buoyed by a perfect five-game homestand, the Denver Nuggets hit the road and kept on winning. Paul Millsap scored 21 points and the Nuggets dominated the second half in defeating the Los Angeles Lakers, who were without LeBron James, 128-104 on Sunday night for their sixth win in a row. ''Our last homestand gave us confidence to come on the road and win,'' Millsap said.
