Even depth-wise, it could be argued that we're barely a top 10 team, let alone the best.
Rose/Hamilton/Hinrich/Robinson/Belinelli
Paul/Billups/Jamal Crawford/Willie Green/Bledsoe
Wade/Ray/Chalmers/Mike Miller/Cole
Nash/Bryant/Barnes/Blake
Westbrook/Harden/Sefolosha/Maynor
Williams/Johnson/Marshon/CJ Watson
Parker/Ginobli/Danny Green/Neal/Mills
Iguodala/Holiday/Turner/Nick Young
Lawson/Afflalo/Andre Miller/Chandler/Corey Brewer
Jennings/Ellis/Udrih/Mbah a Moute (possibly)
Lin/Martin/Livingston/Douglas (possibly)
Plus there's still a ton of quality not on rosters: Arenas, Barbosa, Baron Davis, Farmar, Fernandez, Fisher, Meeks, Anthony Parker, Delfino, Pietrus, Webster, CJ Miles, McGrady
Plus, I probably missed a bunch.
