Were the 2009-10 OKC Thunder the greatest collection of future stars ever?

The SuperSonics/Thunder drafted Durant (2007 1.2), Westbrook (2008 1.4), Ibaka (2008 1.24), and Harden (2009 1.3) as their consecutive 1st round picks in the 3 preceding years, traded for Jeff Green (2007 1.5) the night after the 2007 draft, and acquired Thabo Sefalosha in February of 2009.

Before the 2009 season, those 6 players combined for a win share of 21.0.

Beginning with the 2009-10 season, through today, the accumulated win shares for those players and their rank in the NBA during that stretch:

2. Kevin Durant - 104.9
4. James Harden - 84.0
6. Russell Westbrook - 70.8
24. Serge Ibaka - 50.6
102. Thabo Sefolosha - 28.7
104. Jeff Green - 28.1

Total: 367.1

If you look at other players on their roster during that season, you've got Nick Collison who comes in at 129 with a total win share of 23.9 since 2009-2010 and Shaun Livingston with a total win share of 20.4 since that season, good enough for 157 in the NBA during that stretch.

Of what would become the top 157 players in the NBA (by win share) over the next 7+ seasons, 3 of the top 6, 4 of the top 24, 6 of the top 104, and 8 of the top 157 were on the Thunder roster to start the 2009 season.

Other metrics:

93. Collison
103. Sefolosha
109. Green
198. Livingston

Obviously Durant, Harden, and Westbrook are the headliners, but Ibaka is a top 30ish player as well, and even their bench players became solid contributors. I can't come up with a team having that many future elite-solid players on the roster at once. Any thoughts?
