Granted KD has played 52 games and Lebron has played only 49, but KD has 182 more points, 2 more steals, 19 more blocks, and 34 more threes. Lebron has 10 more rebounds, and 120 more assists.
Agree that the 120 assists probably are worth more than the 34 three and other stats in there (especially with the three game advantage), but I do like the phenomenal FG% for Durant, plus the insane FT%. Lebron's still technically bringing a long a negative FT% value.
Hard to hate either, but one one one right now without considering other players, I'd take Durant by a small margin. Lebron's last week or so's FG% has been great, but his main value comes from the counting stats since his FG% is normally really good anyway (Not to mention he's not shooting it a ton).
