Except that Harden is 24 and already took a team to the finals. Curry is 26 and hasn't done that. Neither has say..a two time mvp like Nash. Sounds like Harden will win more than 2 mvp's in due time.
Also, Harden played better than Curry in their respective final elimination games..
Even in the games he played bad in this series, he was still clutch in most of them. That last game didn't even need for him to be clutch as they found other ways to score already, they just lost it on (lack of) defense.
