Steve Nash is the first ever defensive liability to win the MVP. He's as bad on defense as, like, Voshon Lenard -- and Voshon doesn't even pretend to try. Or didn't in Denver, anyway. Nash is a bottom five defender in this League and that's being generous. Kobe made the NBA All-Defensive team! That's one half of the game where Nash is a liability. It's the half that "wins championships". And Kobe excels at it!
You think he makes his teammates look better... you should see what he does to the guy he's defending!
Luckily this year, Gilbert Arenas sucks at defense too.
