James is second in all time 450 Supercross wins (50), and second all time in AMA outdoor national wins (48). He is also known for innovating the “Bubba Scrub” or just “scrub”, which revolutionized the sport and became a fundamental skill needed to compete in Professional Motocross. He was the first to host his own television show Bubba’s World which brought even more attention to the sport. He is arguably the most financially lucrative racer, bringing in endorsement deals paying him over $10M a year throughout his career.
