That article is a joke. The national media is just crazy these days. First they basically blamed Ginobili for the Game 2 loss when it wasn't anywhere near his fault. Now all of a sudden he has passed Duncan in importance? WTF ?
Yeah, Ginobili was the best player on the Spurs in the regular season. But this is the playoffs now. Duncan, even when his numbers are ugly, is involved in just about every possession on both ends of the court.
Ginobili is a great player and when he's at his rolling he's a top five player in the NBA but the Spurs are best when they don't depend on his production. Ginobili's one flaw as a player is his inconsistency and the Spurs would be in trouble if they need Ginobili to be great every game to win.
I do agree with Duncan that Ginobili's biggest value to the team is scoring when baskets become hard to get and the pressure is on. Ginobili is the ultimate x-factor.
