"I think fighting is a selfish sport. You ain't got time to think about anybody else but yourself, you know? For the training leading up to that fight, it should be all about you, a little bit. Or whoever is the guy fighting. Fight night should all be about you and what you gotta do, and you shouldn't have to be worrying about anyone else. Otherwise, you're not going to be focused on yourself. I don't want that sh*t going on in my head."
-- Anthony Pettis once said he didn't like fighting on the same fight card as his younger brother Sergio Pettis; as having to go out to compete after watching him get knocked out wasn't the easiest thing to do. Now, Nate Diaz explains why he won't ever fight on the same card as his older brother Nick Diaz. In fact, Nate told The MMA Hour (via MMA Fighting) won't fight on the same card as a teammate because to him, that night, and the days leading up to it should all be about you and your task at hand. And if you have to worry about a loved one going through the same vigors and dangers as you, well that's just something else added on to your plate unnecessarily. At the end of the day, says Nate, you have to be a little selfish, because that's what the sports asks of you.
