Tony Parker jumps 12 spots in #NBARank. His future is so bright, he's gotta wear shades. Actually those are to protect his cornea. — Beckley Mason (@BeckleyMason) September 24, 2012

#NBArank Tony Parker could win MVP every year and still find a way to fly under the radar. — Tyler Glass (@irishfan10839) September 24, 2012

Tony Parker's FG% in the paint is better than most big men. His patented floater has been an NBA signature move for years now. #nbarank — Cliff Kim (@CliffMusic) September 24, 2012

Carmelo Anthony | @carmeloanthony

New York Knicks | SF | Age: 28 | 2011 rank: #12

Carmelo Anthony as the 17th best NBA player is fair. He's an elite offensive talent that's terribly inefficient and a poor defender. — Bobby Montano (@bobbymontano) September 24, 2012

ESPN gave Carmelo Anthony more motivation for a career year, in his prime at 28, after ranking the Knicks star at No. 17 in their #ESPNRank. — Michael Scotto (@MikeAScotto) September 24, 2012

So @carmeloanthony dropped to No. 17 in @nbaonespn rankings. What's it mean? Nothing. Melo knows his value now depends on team success. #fb — Alan Hahn (@alanhahn) September 24, 2012

Melo was part of exactly 1 lineup that posted a positive adjusted +/- last year. He played power forward. bit.ly/TrsMsQ — Beckley Mason (@BeckleyMason) September 24, 2012

Melo is No. 17 in #NBArank. If the rankings were just for offense he'd be Top 5. — chris palmer (@ESPNChrisPalmer) September 24, 2012

Melo is No. 17 in #NBArank ... also his number of career playoff wins. — Royce Webb, ESPN NBA (@RoyceWebb) September 24, 2012

Chris Bosh | @chrisbosh

Miami Heat | PF | Age: 28 | 2011 rank: #24

Today's #NBARank reveals confirm Chris Bosh is in the top 20. Amazing what a playoff injury and much-needed comeback will do for a guy. — Adam Reisinger (@AdamReisinger) September 21, 2012

Steve Nash | @

SteveNash

Los Angeles Lakers | PG | Age: 38 | 2011 rank: #14

For his flaws (age, defense), still not sure there's a better pure-shooting PG in the league than Steve Nash. #nbarank — Aaron D. Burgin (@TheFullTimeDad) September 24, 2012

With Nash coming in at #19 and Kobe, Pau, and Dwight yet to be listed, this means #NBARank will have 4 Lakers in the Top 19. Wow. — NBA Guru (@NBAGuru) September 24, 2012

LaMarcus Aldridge

| @aldridge_12

Portland Trail Blazers | PF | Age: 27 | 2011 rank: #23

Lamarcus Aldridge was 20th on #NBARank and its fair. He's in the group of the best PF but someone had to be at the end of the line. — Jay Ramos (@CourtBully) September 24, 2012
