If they face each other, the ref will thow the ball up, the clock will start, and the score will be kept, and the teams will compete and there will be an outcome. Do you really think that Duncan, Parker , Ginobli, and Splitter will be influenced by a game several months ago that they weren't even a part of. The role players ,if they are worth a crap ,will remember and respond with extra effort also and be bolstered by the presence of the core players.
Now if key players are injured for the Spurs they wll lose anyway so what difference would it make. There has to be better points to make.
