It costs 500 VC to donate to NBA Cares. To get this trophy, go to the social media page from your MyCareer menu (Player > Social Media). From there press to boost your popularity, then :L2: or :R2: to get to the Fan Support page, where you can donate to NBA Cares.
There have been reports of this trophy not popping after donating to NBA Cares in both offline and online MyCareers. To work around this, start a new MyCareer (foul out of the Rookie Showcase if you want to get through quickly) and once you’ve been drafted donate to NBA Cares again.
