Probably Anthony Davis. He's the 5th most productive player in the NBA this year, despite missing a dozen or so games, and based on his age he probably hasn't even hit his physical prime yet. His versatility allows him to coexist with any 5.
18.3p, 5.5r, 4.1a, 1.6s, 2.4to, shooting .583 per 36
Those are all-star figures and he's averaging that in the playoffs for his career. He didn't have the good fortune of developing before he started going to the playoffs. He's been going since his rookie year. He's had 1 bad playoff in 5 years (anybody can have a bad 6-game stretch).
