I've broken down the box score from Game 5 from the Lakers' perspective (click on image at left to enlarge).
Yellow is a positive for LA, while red is a negative/concern.
You'll note that not a single Laker bench player got to the foul line. That's remarkable. Further, only four Lakers even attempted a FT. From the field, LA's bench only contributed eight field goals.
But, the Lakers outscored Boston 13-2 in fast-break points and Odom and Gasol's shot selection was excellent.
