UFC is pretty interesting as it appeals to people’s sense of the extreme aspect of sport. I am not sure there is much concern in this sport for the bigger picture, long term perspective. Agents and the management staff would find it easiest to dispose of the talent for younger , fresher players.
I won’t ever forget the player who came to work with Charlie from one of the greatest football clubs in the USA from Texas. He was an amazing athlete and wanted to know how I made such fantastic burgers. ( Yes, I am patting myself on the back here) . He told us he had been a super star his entire high-school career in football, came to the NFL and got injured. He said the entire team was filled with guys just like him only now his career was in jeopardy as they were giving him one last change to get rid of this injury. The team staff had not done the job. He came to Charlie completely discouraged but after 10 days he was as good as new.
I am certain a person could make a career in the niche of educating and supplying therapy and training as a package to some of the UF guys. It might take a bit of time as there is an educating component first , then some practical work and then followed by enough time to show whom ever what you are saying could extend their career in multiples.
The professional athletes who eventually found Charlie understood that proper training, rehab and nutrition was their ticket to a longer , healthier career. Not all coaches, trainers and administrators in sport care about tomorrow. That is the ugly side of professional sport.
