Don't walk through life just playing football. Don't walk through life just being an athlete. Athletics will fade. Character and integrity and really making an impact on someone's life, that's the ultimate vision, that's the ultimate goal - bottom line.

The quote is saying that it’s important to focus on building your character and having an impact on other people’s lives, rather than just focusing on being an athlete or playing a sport. Athletics will eventually fade, but the things you do to help other people and build good character will have a lasting impact and that should be the ultimate goal for everyone.
