Well, unless someone can convince me otherwise, I'm going to stick with my same top two picks from last thread (
mostly, but not entirely, same arguments). 3rd pick is new....
1st ballot: Kevin Durant '14I freely acknowledge the Durant is a completely average defender overall. But: very good to elite as both a rebounder and playmaker for a SF. And then GOAT-level pure scorer: 41.8 pts/100 possessions @ 63.5% TS

. fwiw, I'd also constructed formula founded on Moonbeam's Score+ rating (I called mine "Modified Score+").......'14 Durant is the 2nd-highest MS+ rating on record (just barely behind '88 Barkley, and just barely ahead of '83 Dantley).
He couldn't quite maintain that in the playoffs, but still......35.9 pts/100 poss @ 57.0% TS while playing 42.9 mpg; that's still very elite level scoring, and---collectively with the rs numbers---has him in contention for greatest ever pure scoring season. And bear in mind the defense he was facing in the '14 playoffs:
1st round: -2.1 rDRTG (ranked 7th of 30; being guarded primarily by Tony Allen, who I think is arguably the greatest perimeter man-defender of this generation)
2nd round: -1.9 rDRTG (9th of 30)
3rd round: -4.3 rDRTG (3rd of 30; being guarded by Kawhi Leonard)
fwiw, where portability is concerned, although obviously it's very speculative, I suspect Durant's is reasonably high, as he's primarily an off-ball player (takes less of the table), and---at least in the modern setting---provides a ton of floor spacing, which is quite important. I mean, his defender literally has to be glued to him even 25-26 ft from the hoop, and is basically taken out of help defense entirely.
2nd ballot: Dirk Nowitzki '06Helluv' an offensive anchor, who also must be listed as one of the greatest pure scorers, especially when factoring his ability to hold steady or even scale up in the playoffs. He didn't dwindle in the post-season in '06 while bringing his team to the brink; and I'll be honest, the '06 Finals almost has a small asterisk by it in my mind, as there was some fishy-seeming officiating going on in that one.
Why '06 over '11? I know his post game isn't as refined as in '11, and hasn't figured out how to deal with double-teams quite as well as in '11 either.....but I kinda like the better motor and mobility he had on him in his younger years, like that fact that he could carry the load and have a big impact for 38 mpg (instead of 34) while missing only a single game all year, too. Significantly better rebounder in '06 than he was in '11. And it was my impression of both eras of his career that he was a better defender in '06 (again maybe the better motility and lateral quickness, etc), though I'll admit the impact data does not reflect this opinion.
3rd ballot: Stephen Curry '15Can't decide yet, though I'll say it's primarily between Steph Curry, Tracy McGrady, Chris Paul, and Charles Barkley for me (West, both Malones are in the immediately vicinity, too). Tough decision, I'll take a stand with somebody before closing time.
EDIT: Going with Curry. Reasoning provided in post #28 itt.
