Joint defense, also known as regional joint defense, as the name suggests, players unite as a whole to defend a certain area of the field.

There are many types of joint defense, the main body is 2-1-2 joint defense, and other joint defense can be said to be its derivatives or variants, such as 2-3 joint defense, 3-2 joint defense and the most commonly used 1-2-2 joint defense in the NBA.

The name of these defenses is actually their basic position, such as a 2-1-2 defense, with two players on the wing, near the free throw line at the center, and two other players defending both ends of the baseline.

"How do you get to know the joint defense?" Jiang Lanyue said while standing on the podium of the small conference room, with slides showing on the curtain.

"A lot of people like to draw standing maps like textbooks, just like this slide showing now."

"However, I hope that before you really learn the position and movement, you must first understand the tactical idea of joint defense, any tactic is flexible and changeable, and the only thing that remains unchanged is its core idea!"

"Joint defense, regional joint defense, the word joint defense, very straightforward indicates its basic requirements, any defense, to five players on the field to participate together, any defense is a linkage, this is one of the differences between it and man-to-man defensive tactics."

"This basic requirement is actually its core idea, five defenders must become a net, each player is a node of this big net, and the object of this net is the only basketball on the court!"

"This is the biggest difference between it and man-to-man tactics, the object of man-to-man defense is people, the position of people on the field! And the joint defense is the ball, the position of the ball on the field! ”

"Yesterday I asked you to watch the Warriors in a blurred way, just to make you fully aware that no matter what defensive tactics are, the ultimate goal of defense is to limit 'position'! Whether it's the position of people or basketball! ”

"After understanding this core purpose clearly, let's look at the specific types of joint defense, through the name we can clearly judge its role, 2-1-2 joint defense is the basic formation of joint defense, convenient for various formations, 2-3 joint defense, focus on the bottom line and interior defense, 3-2 joint defense, put pressure on the perimeter shooters, as for the 1-2-2 joint defense is the most suitable for the NBA field and rules of a variant."

Chen Zhi listened carefully to Jiang Lanyue's explanation, he was born in the wild court and knew very little about it, in today's NBA popularity, the wild court is as popular as the NBA, and the influence of FIBA's international rules is much smaller.

Most of the other newcomers to the school team have also received joint defense training in the high school team, and they are no strangers to joint defense.

Jiang Lanyue's carefully crafted slides focus on the net she spoke of, rather than on the position and change.

Chen Zhi observed carefully, and gradually found some doorways.

He found that in the net formed by the joint defense, the one closest to the opposing ball carrier, the one who was responsible for the fewest defensive objects, and those who were far away from the basketball position, were almost all in a position where they could defend two, a kind of middle position that could be very convenient for blocking the passing route for steals.

No wonder Jiang Lanyue said that the five people formed a net to hunt basketball.

It's very graphic indeed.

"Remember, joint defense is always a dynamic process, and the defenders are either on the move or ready to move!"

"In any game, your opponent will not cooperate with you in positioning, and no one will take the initiative to go to the defender and cooperate with the opponent for a 2-1-2 combination."

"Tactics are always changing, and no opponent is stupid enough to let you have one tactic throughout the game, let alone stand rigid because you're executing some kind of joint defense."

"Except for the idea of basketball defense, all joint defense changes according to the situation on the opponent's court."

Jiang Lanyue spoke eloquently, quite sure of her own views, and she repeatedly took the trouble to emphasize thoughts, change, and movement.

"The reason why the 2-3 joint defense is called the first god formation in the CUBA arena is because CUBA is only a semi-professional league after all, and there is still a big gap between the stability of the outside line and the CBA, especially the NBA."

"Using 2-3 or 2-1-2 can limit the opponent's interior attack to the greatest extent, while conserving our physical strength, after all, the physical strength consumed by man-to-man defense is greater than that of joint defense."

In Jiang Lanyue's concept, it is obvious that there is no substantial difference between 2-3 joint defense and 2-1-2 joint defense, the difference between these two joint defense lies in the position of the center, no center will always stand rigidly under the basket in defense, and the two joint defenses are regarded as the same kind, and the problem is not big, 2-3 joint defense can be said to be the simplest change in 2-1-2 joint defense, especially when the center moves faster.

No wonder after communicating with Jiang Lanyue, Zhou Jian's training for Lu Taishan, the big center, focused on strength and running, this guy was indeed a lot faster during this time, Chen Zhi After listening to Jiang Lanyue's explanation, he couldn't help but suddenly feel that Jiang Lanyue had considered every step after the school team.

"The joint defense is more about tacit understanding and timing, and understanding your teammates is the key to forming a chemical reaction on the defensive end, and the tacit understanding can be cultivated on the defensive end in order to really run the joint defense well."

After that, the members of the varsity team began to conduct joint defense drills.

Chen Zhi found that this tactic can indeed be very troublesome for ball carriers, especially for a point guard like him who breaks through to the basket and makes it difficult to divide the ball again after rushing into the interior, as if getting into a pocket that has been put away, and it is especially easy to make mistakes in passing.

This kind of joint defense is very useful against teams that don't shoot well, and it is very effective in protecting defensive rebounds.

However, its shortcomings are also obvious, and it is easy for outside players to get shots.

After rushing inside a few more times, Chen Zhi tried to change his strategy, no longer rushing into the inside line, but pretending to break through between the two defenders in front of him to attract the opponent to close the door and defend, and then split the ball to the left and right wings, making it more difficult for the two defenders on the outside to make up for the defense.

The wings of the three-point line are precisely this defensive flaw of the 2-3 team.

However, this does not seem to be a flaw, because defending this kind of joint defense itself is based on the situation where the opponent's projection is relatively poor.

After that, Jiang Lanyue began to add defensive joint defense and broken joint defense to the team's tactical training.

Among them, the 2-3 joint defense is the focus of the team's tactical drills.

In the final analysis, there is only one way to crack the 2-3 joint defense, and that is to shoot.

Li Xuedong's existence is a big threat to the 2-3 joint defense itself, unless his hand really drops to the freezing point, I am afraid that no team will dare to sacrifice 2-3 joint defense against Yangda.

After learning from Song Lei's amazing appearance rate of this 2-3 joint defense in CUBA, Chen Zhi began to continue to practice shooting, especially the emergency stop jump shot, but compared to the powerful training function in the ball soul system, his progress speed is simply negligible.

But this ball soul system really made him scratch his head, and he didn't know how to get various training cards, if he could get a shooting training card, even if it was just low-level projection training, it would definitely make his projection strength go up a big level.

During the break, Chen Zhi opened the ball soul system and was surprised to find that the soul power value had reached more than 8,000, and he could soon carry out the next low-level enhancement.

He couldn't help but sigh at the strength of the soul power harvesting system.

When you go to the CUBA competition, there are thousands of spectators in attendance, and you are looking forward to it.

After the last low-level bounce enhancement, Chen Zhi found that the mid-level bounce displayed after that had been in a gray state, and after studying for a long time, he didn't find the activation conditions, and the amount of soul power required for the mid-level bounce was unknown.

It will probably take all the low-level enhancements to complete before it can be activated, Chen Zhi can only guess so.

While Yangda is preparing for the CUBA Lu Provincial Grassroots Qualifiers, other colleges and universities that are qualified to participate in the men's Group A competition are also working hard for this.

The two strongest teams are naturally the traditional powerhouses, the University of Science and Technology and the Agricultural University.

The main campus of HKUST is located in Qingcheng on the coast of the Yellow Sea, which was once the absolute hegemon of the college basketball industry in Shandong Province, and won the championship of the college basketball tournament in Shandong Province for 13 consecutive years!

It also has a pretty good record in CUBA, with 9 times in the national quarterfinals and the overall championship in the 4th CUBA League.

However, with the changes in the admissions system in recent years, HKUST's performance in CUBA has become more and more unsatisfactory.

The 15th CUBA League won the 6th place in the Northeast Division, the 16th CUBA League won the 5th place in the Northeast Division, and the last edition won the final ranking with Yangda and ranked 7th in the Northeast Division.

I haven't been able to reach the semi-finals of the regional competition for several years, so naturally I don't have the opportunity to participate in the national competition.

Moreover, its position in the province has also been strongly challenged by the late star of Agricultural University, and the rise of Yangda last year has made HKUST feel more and more threatened.

However, in the grassroots qualifiers of Lu Province last year, he still beat Agricultural University to enter the regional competition as the first place in Lu Province.

On the other hand, the headquarters of Haoqiang Agricultural University is located at the foot of Mount Tai in Dongyue, and after the University of Science and Technology lost its dominant position, it has entered the CUBA Northeast Division Competition with the first place in Shandong Province for three consecutive years.

In the 15th CUBA League, it was Nongda who beat the University of Science and Technology of the same province to win the final qualifying round and win the fifth place in the regional round, but this ranking was just excluded from the national round of 16.

The 16th edition of the CUBA League also ended in the quarterfinals of the division.

Last year's 17th competition was even worse, encountering Jinghua University in the first round, losing by 9 points after a hard battle, and finally ranking only 12th.

However, in the 18th CUBA this year, Agricultural University is likely to overtake HKUST again, because the absolute core of HKUST, Li Jun, who can score an average of 28 points per game, graduated and retired like Li Wei after the 17th CUBA!

This will inevitably make HKUST's strength this year much less.

On the other hand, Agricultural University, although it has also lost the main player Song Linyan, the main framework of star player Zhao Yunlong and inner twin towers Ren Weiyao and Luan Xiaojun is still there.

In the face of this year's Agricultural University, the University of Science and Technology will inevitably be under a lot of pressure.

However, even so, HKUST is still bound to win a place in this year's Northeast Division.

Yangda, which rose last year?

They seem to be worse than HKUST, the main center and the main scorer retired together, it can be said that they returned to the pre-liberation overnight, how much of a threat can they have to HKUST!
