Here is the full list of voters from ESPN.com, the TrueHoop Network, TrueHoop TV, Daily Dime Live, ESPN TV, ESPN Radio, ESPN Deportes, espnW, ESPN The Magazine, ESPN Insider, ESPN Fantasy, ESPN Games, ESPN Dallas, ESPN Los Angeles, ESPN Chicago, ESPN New York, ESPN Stats & Information, ESPN Topics and ESPN Analytics.

Apparently the "everything" in Kyle Lowry Over Everything doesn't apply to 50 players. #NBARank #KLOE — Adam Reisinger (@AdamReisinger) September 17, 2012

Nene

Washington Wizards | C | Age: 30 | 2011 rank: #31

@nbaonespn Nene and John Wall might be a sweet lookin pick n roll tandem. But Nene needs to play some d! #NBARank — Grant Bosiacki (@GBos2) September 17, 2012

Big fan of Nene's game. Beast. Ferocious. Warrior. I mean, the dude had a tumor removed, and came back stronger! #nbarank — Cliff Kim (@CliffMusic) September 17, 2012

Paul Millsap

Utah Jazz | PF | Age: 27 | 2011 rank: #57

@nbaonespn Paul Millsap 53. That's the highest you're going to see any player this year who should frankly be a backup. #NBARank — Mark D. (@blazers6thman) September 17, 2012

Millsap at 53 in #NBArank... Too high, too low or just right? RT @nbaonespn: #NBArank 53: Paul Millsap. bit.ly/2012NBArank51-… — Utah Jazz (@utahjazz) September 17, 2012

Danilo Gallinari | @gallinari8888

Denver Nuggets | SF | Age: 24 | 2011 rank: #68

@nbaonespn Unfortunately for Danilo Gallinari his ranking was hurt by his play after coming back from injury. #NBArank — Tsuf Bechor (@Tsufbechor) September 17, 2012

@nbaonespn not so sure about Danilo Gallinari at #54 if he's consistent and continues to improve he might break top 50 #NBARANK — Blaze Gunn (@Chaoticblaze27) September 17, 2012

John Wall | @John_Wall

Washington Wizards | PG | Age: 22 | 2011 rank: #40

John Wall's drop in #NBArank is an indictment on the Wizards organization more than anything else. He improved last season amid the chaos. — D.J. Foster (@fosterdj) September 17, 2012

John Wall took a Tyreke Evans-like step back during 2nd year, but Year 3 looks more promising with better personnel around him.#nbarank — Aaron D. Burgin (@TheFullTimeDad) September 17, 2012

David West | @D_West30

Indiana Pacers | PF | Age: 32 | 2011 rank: #45

Said Frank Vogel: "David West is a bad man." He's pugnacious & scrappy, but fundamentally sound & a great leader on a young team. #NBARank — Jon R. LaFollette (@JonFilet) September 17, 2012

Surprised to see David West (#56) ahead of Elton Brand (#85) in #NBArank. Similar stats offensively, but Brand is a far superior defender. — D.J. Foster (@fosterdj) September 17, 2012

Marcin Gortat | @MGortat

Phoenix Suns | C | Age: 28 | 2011 rank: #86

@nbaonespn let's see how Marcin Gortat keeps up without Steve Nash. Much deserved #NbaRank for his consistency on both ends of the floor. — Jean Gabriel Madera (@JeanMadera23) September 17, 2012

Andrea Bargnani | @AndreaBargnani

Toronto Raptors | C | Age: 26 | 2011 rank: #81

@nbaonespn after a healthy year with a better cast around him @andreabargnani will be 20 spots higher next year #NBArank — Alex Audino (@A_Audino) September 17, 2012

Andrea Bargnani rises 23 spots despite an injury riddled season, and rightly so, the Raptors are visibly better with him. #NBArank — Adam Koscielak (@AdamKoscielak) September 17, 2012

David Lee | @Dlee042

Golden State Warriors | PF | Age: 29 | 2011 rank: #54

@nbaonespn David Lee's ranking should be much better, the guy basically averaged a 20-10. #nbarank — Tsuf Bechor (@Tsufbechor) September 17, 2012

@nbaonespnvoters will have David Lee 20 spots higher next year if the Warriors can somehow make the playoffs #NBArank — Brian Deiters (@BDeiters35) September 17, 2012

Brook Lopez

Brooklyn Nets | C | Age: 24 | 2011 rank: #51

Expect this to go way down now that Brook is healthy with tons of talent around him RT @nbaonespn #NBArank 60: Brook Lopez. — Dan(@DanBKNets) September 17, 2012
