I love sports. Any way to test yourself, or others, allows for camaraderie. In the past, sport related posts have languished, so I will make this an open discussion. Any moment, any sport. I can make some suggestions.
BOXING:

Jackie Robinson is signed by the Red Sox in 1945, instead of being thrown off the field.
