This list of 500 is great for the readers and by removing some of these players would be a disservice to the readers. For example, Deion Sanders player baseball for a few years and was known for one thing, stealing bases! He would be removed from this if it is cut down. He was a great base stealer but cut his baseball career short because he wanted to concentrate on his NFL career. HOFers are relevant because it shows that these players weren't just great hitters but they could also steal bases which further helped their HOF status.
