I think you could realistically argue that Harden is having the greatest offensive season in league history (yes even greater than Wilt's 50). Not just the points, but the efficiency, assists, his FTr, etc. And scoring that many on just 24.7 shots, gives him 1.47 pps which is certainly up there among the elite seasons all time (Curry and Durant both had over 30 and a better pps, but Jordan's best he never did, and Wilt's 50 was significantly lower on account of his poor FT shooting). It really is a truly amazing season.
