#2. Court McGee
After defeating Ramiz Brahimaj at UFC on ESPN 32, he gave a tearful speech during a post-fight interview when explaining sobriety and his growth from addiction.
McGee is over ten years free from drugs and alcohol and could not be more proud of his accomplishments. Of course, winning fights is one of McGee's main focal points, but educating and speaking to people who can potentially be affected by addiction is his top priority. He has his own company called The McGee Project, which is dedicated to reaching out to schools, colleges, gyms, and anyone who will listen to his motivational stories and advice to conquer the disease. There is only one message attached to his campaign, i.e., recovery is always possible.
