This is Jamani Swanson and he plays in the Venice Basketball League, a league that "combin[es] the hardcore reality of the outdoor street basketball lifestyle with the glamour and glory of a professional league." He is also a little person.
Of course, this a highlight package so, yeah, he's probably not as unstoppable a force as he looks, but his game is undeniable. You can watch him drive the lane, drill some threes-pointers, cross guys over and assist on an alley-oop or two. "Don't believe in the height, believe in the hype."
