Sure, I like to win when I play basketball or board games or video games, but my day isnt ruined if I lose. Im always up for a rematch. In all seriousness, thats something thats nice about maturing.
I believe that good defense embodies seven cardinal principle: reduce the number of your opponent's shots; force your opponent into low percentage shots; control everything within 18 feet; eliminate second shots; no easy baskets; point the ball on all long shots; and prevent the ball from going into the pivot man.
