Least we ain't burning up
The last sentence meant basically what you said in ur first sentence (all three are on the same level offensively).Didn't understand your last sentence but Curry is definitely on the same level as both (and probably better than Lebron) offensively
Defensively, Steph is not that far from them either. KD had his best year defensively last year with GS and Lebrons defense has always just been about a chase down block.
None of them are Kawhi level defense. NONE
But overall, Curry is on the same level of both regardless of what people think. Better, maybe not, but definitely on the same level
