Kobe Bryant

Can I jump over two or three guys like I used to? No. Am I as fast as I used to be? No, but I still have the fundamentals and smarts. That's what enables me to still be a dominant player. As a kid growing up, I never skipped steps. I always worked on fundamentals because I know athleticism is fleeting.

Boxing is like chess. You encourage your opponent to make mistakes so you can capitalise on it. People think you get in the ring and see the red mist, but it's not about aggression. Avoiding getting knocked out is tactical.
