Ben Simmons has a new team -- no he hasn't been traded (yet) ... the NBA superstar has joined the world-famous FaZe Clan!
Simmons -- a hardcore gamer -- is the newest celebrity investor and even got a new FaZe nickname to go along with it ... FAZE SIMMO!
The Philadelphia 76ers big man will serve as an "ambassador to the organization for content as well as an advocate for gaming and esports and the expansion of FaZe Clan globally," the company says.
FaZe Clan also notes it will not disclose the amount of Ben's investment, though it's probably fair to assume it's a sizable number.
