Mason Gordon’s dream is to create a new global team sport, something that hasn’t happened since basketball came on the scene in the 1890s. But Mason is determined. He invented Slamball—an amped up combination of basketball and football that’s played on trampolines—nearly twenty years ago. He had some splashy early success and got two seasons on TV. And then Slamball seemingly disappeared. But Mason is still at it, and now Slamball is surging in popularity on the other side of the globe.
