Leon Jones
Leon Jones, founder and creator of Rumbleball, is a lifelong multi-sport athlete and visionary dedicated to expanding opportunities for competitors everywhere. A former basketball player at the University of Michigan, Leon also excelled in football, baseball, and track during high school — experiences that shaped his deep understanding of athletic versatility and competition.
After years of witnessing countless talented athletes left without opportunities to continue their athletic journeys — not because of a lack of skill, but because of limited access and opportunity — Leon set out to change the game.
Rumbleball was born from that mission: to build another field for athletes to play on. By blending the best elements of multiple sports, Leon created a new arena where athleticism, creativity, and passion meet — and where deserving athletes can once again showcase their talent at the highest level.

About Rumbleball
Rumbleball is a new, full-contact hybrid sport that blends the intensity of football, with the precision of baseball. Built for athletes, by athletes, Rumbleball gives competitors and fans something bold, fast, and entirely new.
Created to fill the gap in athletic opportunity, Rumbleball offers a platform for the countless talented players — from college to semi-pro and beyond — who haven’t had a fair shot to compete, not because of ability, but because traditional sports offer too few spots.
Rumbleball provides that chance. It rewards speed, power, and smart play, giving athletes a new path to professional competition and fans an electrifying new game to follow.
Played on a six-base field known as The Crown, Rumbleball delivers nonstop action, dual scoring, and high-energy gameplay that keeps both players and spectators on the edge of their seats.
Rumbleball — Built for Athletes. By Athletes. For the Fans.
