Duncan has and will always be better than Kobe. Unfortunately, MVP is chosen by season performance and Duncan doesn't need to even wake up during the season. It's guaranteed the Spurs will make the playoffs and Duncan plays his best there.
Either way, Chris Paul was robbed. I'm pretty sure the people who made this decision only considered that the Lakers did better this season. What they didn't analyze is because the Lakers have a better team this season. Hornets run through Chris Paul. If Paul does bad, they do bad. If Paul does good, they do good and he lead them to only 1 game behind the Lakers. You figure out the rest.
No point in arguing with Lakers fanboys though. They've been riding Kobe's ever since he came in the NBA, even when he's was shooting airballs, so you're not going to convince them even with facts.
