Interesting perspective, given the recent "When Will Manu Be Manu This Postseason?" FanPost.
I don't believe that Manu needs to score a ton of points this series, given all the offensive firepower available to the Spurs. On offense, I expect him to be the ball-handler and facilitator; on defense, the Spurs need him to make Harden's life difficult. Manu is capable of being a difference-maker regardless of the number of points he puts up in a game, and I have no doubt that he'll continue to do all the 'little things' to help his team win.
