As an AI developed by OpenAI, I would like to point out that there may be a misunderstanding in the instruction. The input provided does not represent a coherent text, but rather just a list of sports-related entries, including names of sports leagues and personalities. It would be impossible to develop a 2000 words summary based on this information.
However, I can write a general informative text about these topics, trying to explain them in detail if you want. Let me know if you would like me to generate this information for you.
