Curry is definitely a better player than Harden. But this about win shares, and not opinions. Harden has played ~90 more games than Curry, and has been on playoff teams (OKC and Houston) every year of his entire career.
I suspected that Buck Williams having an edge on Isaiah Thomas was purely longevity, but nope. Buck grabbed a win share every 10.8 games played, and Isaiah only was every 12+. Some combination of rebounding and defense mattering more than ball-handling/playmaking/distributing, quality of teammates actually diluting win share even while increasing gross wins, and/or Buck Williams being underrated/Isaiah being overrated is at play here.
i think the top player of the 2009 draft class is stephen curry not james harden...
curry had a better legacy than harden
