The most important things to play basketball are: skill, basketball IQ and physical fitness. Technology is divided into attack and defense. No matter how strong the player is, he can't defend, and no one wants you. A player who attacks the top and defends well like Kobe Bryant is the "best" in basketball. A player with top defense and poor attack is called "blue collar". Although he is not remembered by fans, he plays a huge role in the team. A team with excellent defense must be a strong team, but a team with excellent attack is not necessarily a strong team. Therefore, defense is more important than attack in basketball. Basketball IQ is very important. A basketball team with high IQ can perform well even if its skills and physical fitness are not very good. He will execute the tactics given by the coach well, and he needs basketball IQ for both offense and defense. Physical fitness is very important All the big-name NBA stars have excellent physical fitness. Physical fitness generally refers to strength, bounce, speed and physical strength, as small as wingspan, bounce speed and body flexibility. An outside player has these, he must be a superstar, Kobe and Wade have these lineages. James has poor physical flexibility, but better strength and physical strength. The strength of inside players is more important, because they are all big men, so their speed, physical flexibility and even bounce will be relatively poor. Howard is the best representative of the excellent physical players inside. He has excellent jumping ability and is the best among the players with poor physical fitness. His speed and physical flexibility are excellent among the inside players, and his strength and physical fitness are the top in the league.
