2006 - I'd probably put Rondo over Lowry. At his prime, Rondo was a much, much better player than Lowry's prime.
2007 - That's a good ranking.
2008 - I think Rose is too low. He was an MVP and multiple time All-Star before his injuries. I think he's definitely above DJ, maybe even Love, too.
2009 - That's a good ranking, though it could be argued that Griffin and Harden should be switched.
2010 - This one is tough, because those first three could go in any order. I'd honestly probably be fine with either George or DMC at number 1, and Wall could even have an argument there, too.
2011 - I think it goes Leonard, Klay, Butler, Irving, IT. As others have said, Leonard and Butler being excellent two-way players gives them the benefit of the doubt over Klay and Irving/IT, respectively.
2012 - I think Crowder and Beal have just as much of a claim to number 5 as Harrison Barnes.
