Nice idea, would love to own a stake in a sport entity. If you're looking to do a comprehensive market research, asking random questions on here isn't the best way to go about it. You should define the opportunity you're offering investors in a clear and concise manner. Develop your research plan, hire someone (i can help here) or a firm to help. Collect as much information as you can an organized manner - e.g questionnaire. Analyze your data and you're good to go.
