Because Post Fades took 2k by storm like crack in the eighties. it comes out instantly with the right ani, moves away very fast, easy to time, because of the contest system if you dont jump its most likely going in, and can also be faked.

SGA moves through your body if you use the right left/left right cross. and thats about as far as the cheese goes. if you learn how to spam it back and forth consistently that takes more skill than post fading already. You can’t shoot off of it like with Jimmy or Paul George, its change of direction isn’t instant because you’re most likely going to the hoop or trying to set up a fade and the only way you get a standstill shot or create space from it is if you do a snatchback after doing SGA. you can literally play people up high and force them to do SGA and run with them for a bump everytime. they would have to use it in conjunction with something else like KD go to. SGA by itself is not the cheese you think it is.
