The methods of literature, RSR and video observation were used to evaluate and analyze the offensive and defensive ability of CBA teams in the 2022-2023 season, so as to provide reference for each team to improve its competition ability. The results show: (1) The attack and defense ability of Liaoning team reached the level of A in the regular season and playoffs, which is consistent with the strength of the championship; the attack and defense ability of Beijing team reached the level of A in the playoffs; the performance of Zhejiang team was unstable; the attack and defense ability of Zhejiang team reached the level of D in the regular season; the attack and defense ability of Guangdong, Guangsha, Guangzhou, Shenzhen, Shanghai and Xinjiang team reached the level of B. The rest of the team’s offensive and defensive capabilities in C, D or regular season and playoff offensive and defensive performance difference is large, of which Liaoning team has a very good performance at both ends of the offensive and defensive, Shenzhen team failed to continue to maintain the offensive momentum of the regular season, poor performance in the playoffs. (2) In terms of attack, Liaoning Team, Guangdong team, Guangsha team and Guangzhou team played a steady and brave, and performed well in the regular season and playoffs. On the contrary, Zhejiang, Shanxi, Shandong team in the regular season offensive ability to reach the B level, but with the intensity of the playoffs and performance decline, the entire season no team’s offensive ability to reach the A level, the strongest offensive comprehensive ability of Nanjing team. (3) In terms of defense, only Liaoning team reached the A level, there are six teams reached the B level, and most of the teams have average defensive ability. The correlation analysis shows that the offensive, defensive and comprehensive abilities of each team are positively correlated with the team results. It is suggested that each team should carry out targeted practice on attack and defense ability, pay attention to the balanced cultivation of attack and defense and the high-intensity confrontation practice to improve the stability of attack and defense.
