As fighters, the stark reality is, there's times in that cage when we want out. There's times when we've had enough and we want out, and we're able to recognize defeat.

Very normal trajectory of a fighter's career - you start out fighting at the YMCA. You move on to the dog park. You get into a coliseum. On your way out, you go back to the YMCA, and then you finish up at the dog park.
