The Boston Celtics and Los Angeles Lakers do have a way of moving the storyline forward, but their Saturday matchup in Los Angeles will have a hard time topping even the most recent meeting between the teams in Boston. Point guard Rajon Rondo pulled out a 129-128 victory for the Lakers on Feb. 7 with a buzzer-beating shot on the floor where he led the Celtics to the 2008 title over the Lakers in the NBA Finals. The Saturday version of the cross-country rivalry will pit a Celtics team finally gaining traction after a rough post-All-Star break run against a Lakers team that is slipping further out of playoff contention with each game.
