Utah Jazz star Rudy Gobert says the NBA can come knocking on his door any time it wants ... telling TMZ Sports he ain't scared of the league's "random" drug tests!!
Of course, it's become quite the trend in the Association -- you post a jacked pic on Instagram, you get "randomly" hit up for a test.
Just ask Sacramento Kings guard De'Aaron Fox, who posted a shirtless pic showing off his buff bod in the gym earlier this month ... and then got contacted the very next day.
