Fortunately, thanks to his historic $303.7M contract, he's got plenty of money at his disposal to both have fun, and give back to the community.After it was announced that Brown had signed the massive agreement, he addressed the media where he announced his plans to give back. Boston Celtics v Sacramento KingsWhile speaking to CBS Morning's Dana Jacobson, Brown opened up on why giving back to the community is so important to him:"I think that being an athlete, you have a lot of influence in your community and if you use it responsibly you can make the world a better place. Communities need people to represent them."He continued:"They feel discluded, so me being from those communities, just because I escaped those barriers that allowed me to make it to the NBA doesn't mean I'm going to forget about the groups I came from. I'm just trying to help as much as I can and just ultimately make the world a better place."As Brown went on to explain, his multi-year plan revolves around bridging the wealth gap in Boston, which consistently ranks in the top five for income inequality yearly.With plenty of big plans on the horizon, the player will have the chance to keep the momentum rolling when the NBA season tips off in October. After coming up short in the Eastern Conference Finals, only time will tell whether Jaylen Brown and the Celtics are able to make it to the NBA Finals.
