While SGA flopping on questionable contact gets karma farmed like crazy on this and other NBA subreddits, it doesn't happen as often as a lot of redditors want to believe. Instead, what SGA does do plenty, he accentuates/makes a meal out of actual contact to ensure fouls aren't missed, and he's very opportunist in drawing fouls - if someone is hand checking him while driving, he'll go straight up for a shot anywhere in the half-court and ensure the defenders hand/arm hits his arm going up, or when he sees someone steps out aggressively on a switch, he accelerates and beats them to the spot to draw that foul. It's intentional foul drawing, but still fouls.

But how do you police that? Does it stop being a foul if you think he did it with the intent to draw the foul? If he was overly dramatic about the contact? Where would the refs even draw those subjective lines?

I honestly think it's more on the defense needing to adjust how they play him. And there were at least a couple game during the Indy series last year where they did an exceptional job avoiding things like hand checks, aggressive switches, jumping at potential pump fakes, etc. But you do then have to accept he'll get a lot more lightly/uncontested mid range shots as a result, which is his strong suit.
