Something just occurred to me. Can you imagine how motivated the first black athletes who were allowed to play integrated sports against white people must have been?! You've been treated like a worthless animal for centuries and then suddenly you get to play a contact sport against the very people who have been abusing and oppressing you?!
As a Jew, this made me think of how amazing it would feel to play tackle football against an entire team of Nazis...although if that happened it would mean that the Nazis won, and that wouldn't feel very good at all. Damnit.
