I tend to agree with Nash. His team would have won the title without the ludicrous suspensions of Diaw and Stoudemire, or the fluke injury to Joe Johnson. How should those events, completely independent of Nash, affect the determination of Nash's abilities? Every TEAM gets some breaks that help win a title, or has some unlucky breaks that prevent them from doing so, independent of the quality of the players.
KG never gets traded to a decent team. Now he's a better player?
PJ Brown isn't bought out, signs with the C's, doesn't save game 7. Pierce, Ray, and KG are now worse?
Kobe was a different player last year than now?
Bynum is healthy all of 2 seasons ago, maybe the C's never win. Fluke circumstances, independent of all other players.
