The Research On Without Ball Screen In CBA Top Four Teams In 2017-2018 Season

As an important means of the overall cooperation of the whole team,the without ball screen is an effective cooperation method to obtain attack time and space and create offensive opportunities.In the face of the increasingly fierce defense,it has been widely used by professional teams.The effect is outstanding.With the rapid development of basketball in the world,the cooperation form of without ball screen is uncertain and unpredictable,which is paid more and more attention by coaches and players.This paper uses the methods of literature,questionnaire,video observation,mathematical statistics and logic analysis to study the game of the CBA top four teams in the 2017-2018 season.The proportion,the area,the form of continuous application and the effect of the without ball screen are analyzed and studied,and the following conclusions are drawn:1.As the area of the top four teams use without ball screen,the restricted area,the left of low area,the right of low area is relatively more,the high position area is less,the higher area has less or even no without ball screen cooperation.2.It is most common for two to continue to cover for one person and one person for two people continuously.The cross without screen cooperation between three or four players is more and the effect is better,and the continuous without ball screen between two men is relatively rare.There is very little or no screen for one person without ball for three people and for one person without ball for three people in succession.3.Through the without ball screen cooperation,the most obvious effect is to create catch opportunities for the sheltered players,and it is easy to make a profit for the cover players.A considerable part of the screen without ball cooperation has played a transitional role,which makes the team benefit indirectly.Because the quality of cover is not high and the field of vision of the ball holder is not wide enough,thenumber of invalid screen cooperation without ball is more.4.The covered players mainly move to the ball with the help of the without ball screen,the movement of far away from the ball is relatively small,after the covered players catch the ball is mainly passing or dribbling to observe the situation of teammates on the court.The number of direct shots or breakthroughs after taking the ball is small.5.The top four teams all have perfect offensive tactics system,have better players in each position,the offensive tactics system includes a large number of screen without ball cooperation,and has the bench depth superiority.These are important guarantees for the top four teams to reach the semi-finals and even the final.
