09 is definitely underrated
Tier 1 - Curry, Harden, Griffin
Tier 2 - Teague, Lawson, Jennings, DeRozan, Holiday
Tier 3 - Rubio, Gibson, Collison, Evans
Tier 4 - Meeks, Carroll, Green, Hill, Thornton
Pretty solid draft overall. 6 guys have already made all star teams (Tier 1 guys and Teague, Holiday, and DeRozan). The "tier 1" guys all appear headed to the HOF and all certainly could win the MVP (I expect Harden to win this year). Lawson and Jennings look like potential all stars. There are also quite a few other players not even listed with solid NBA careers (like Hansbrough, Jerekbo, Blair, Beverly, Cunningham).
That said Lebron James is the greatest player of his era and one of the greatest ever. Wade, Bosh, and Anthony are sure-fire HOFers. 5 other players from the 2003 draft have made all star teams (West, Kaman, Howard, Korver, and Williams). A number of other players had multiple seasons of being starters and/or key contributors to good teams (Perkins, Pachulia, Diaw, Hinrich, Bonner, Collison, Blake, Pietrus, etc.).
Also, I'm not really sure 2009 is even better than 2010 (another underrated draft). George, Wall, Cousins, Monroe, Favors, Hayward, Bledsoe, Stephenson, Davis, Turner, Bradley, Booker, Vasquez, Fields, Patterson, etc. (even Larry Sanders was in this draft). Heck who can forget Hassan Whiteside and his miraculous season. Still a bit early on this one, but George was a MVP candidate last year, Wall is one of the best PG's in the game, Cousins is the best center in the game, and Monroe, Favors, Bledsoe, Hayward, and Stephenson all have all star potential.
