After the "super star" MVP category of Lebron, KD, CP3, Dwight, and Kobe, it's hard to really rank guys like Rondo because there are so many great all-star level players.
I thought ESPN did a pretty decent job with their rankings before the season, which put Rondo at number 11. Seems pretty fair to me...I don't think he's been a top 10 player this season (IMO it's been Lebron, KD, CP3, Melo, Harden, Parker, Westbrook, David Lee, Duncan, and Kobe) but he's on the edge of that group with guys like Wade, Irving, Griffin, Bosh, Randolph, Curry, Love, Tyson Chandler, Marc Gasol, ect.
