Gelguric gave all the players here a problem, in fact, in his mind, this problem is also unsolved. In his more than 30 years of basketball coaching career, he has long been convinced that in this game, there are ultimate players, there is no ultimate tactic, and any tactic needs to be based on the player's play, daily training and coach's command.

Without these, those tactical roadmaps that look good on paper may be a complete mess in actual games, and many young coaches or college coaches who have entered the NBA have suffered losses, thinking that by following the exquisite tactics on the tactical board to let the players run, and implement his defensive strategy in defense, they can become a strong team.

In fact, basketball is more than just a simple run of two tactics, especially in the NBA, where talent is rampant and money is the case, wishful thinking of building a team to win games as if it were a video game, will only lead to a big fall. Therefore, after so many years in the NBA, Gelguric has always been just an assistant coach, in fact, with his qualifications and ability, he is fully qualified for the position of NBA head coach.

But he just doesn't want to be a head coach, he just wants to be an assistant coach in charge of more technical projects, and watch guys like Rick Pitino break his head in the league and make a fortune himself, while becoming one of the highest-paid assistant coaches in the NBA, and at the same time opening training classes in the summer to lead students to collect tuition, and have a good time.

Of course, Gelguric is not just joking with this question, on the contrary, he knows that in such a training class, it is pointless to teach these coaches about some tactical use, these things are all familiar to everyone, and it is a waste of everyone's tuition fees to take them out and chew them again. Only this kind of challenging, unsettled problem in the basketball world can stimulate their creativity and thinking ability.

You know, with the development of rules, player ability and high technology, basketball tactics are also constantly reforming and improving, although the basic types of tactics have been finalized in the past three or four decades, but different tactical combinations have infinite possibilities. Famous coaches in the past often have tactical labels attached to them, such as Winter's triangle offense, Sloan's UCLA, Adelman's Princeton, Riley's Show-time and the Muscle Army.

But nowadays, there are fewer and fewer such labels, and it is difficult for people to summarize the style of a coach in terms of one type of tactic, and they often combine a variety of tactics to use for their own team, and the tactics will change when the team changes. Like Gregg Popovich, coach of this year's championship winner Spurs, it's hard to label him with a certain system of play.

Gerguric sees this trend, so he asks his students to think, and there may not be a final answer, but this process will give them a better understanding of the tactics and be able to use them more flexibly in the future.

On this ultimate defensive problem of Gelguric, the five students began to sit on the ground, each with a tactical board in front of them, and fully began to brainstorm, not caring whether it could be achieved or not, but imagining in their minds how to pinch the two together.

"I think one of the principles of the amoeba can be changed, and that is the pressure of the defender on the opponent's first shot. We know that the defensive commitment ratio of guards is very low, and it is a big waste to have the team's point guard spend a lot of energy on the outside to block a shot that the opponent may not be a threat. It's better to leave this task to the frontline players and test the pressure to the ball carrier through small rotations, but without disrupting the defensive formation......" Bernie Bisketaugh's son, J. Bisketaft, was the first to offer his opinion.

Although his theory of low point guard defense investment ratio is correct, he does not see that the double guard pressing the first ball is the core of the amoeba defense, without which the amoeba defense will no longer exist, and it is no different from other ordinary rotation defenses.

The other four seasoned guys laughed at Bisketaf's opinion, and Gelguric bluntly pointed out that Bisketaw's idea was basically stuck in the 1980s, and it basically had no practical meaning, because it became a different kind of defense at all.

Mike Brown has been with Popovich for a few years and has helped the Spurs a lot on the defensive end, and he has a deep insight into defense, and he thought for a while and said: "The key to the combination of the two defensive strategies is to find the overlap of the two strategies, such as the problem of strength, some details of the pressing intensity and pressing direction selection in the amoeba defense can be used as a reference for man-to-man defense." The stretch and defensive toughness of man-to-man defense can actually be reflected in the amoeba defense, but it is destroyed by frequent packing. ”

Gelguric nodded to Mike Brown's thoughts, his principle of "merit-based" is already very similar to the tactical choice of modern basketball, which is undoubtedly the essence of following Popovich.

It's just that Mike Brown put forward some ideas and suggestions, but didn't really give a solution, after all, in the process of coaching the Spurs, they have Duncan, a super defensive interior player who has been encountered once in 30 years, and many times his presence makes it easy for the Spurs to build a defensive system. Duncan alone is most of the system.

Stotts hasn't spoken much, his interest is mainly on the offensive end, and he himself is determined to build the ultimate offensive team, and he doesn't know enough about defensive issues to make small comments in the corners.

Carlisle pondered for a long time with a calm face, and finally said: "I don't think it's a problem that can be solved through skill and integration, the difference between the two tactics is too great, especially some principled differences, such as how can man-marking and bag coexist perfectly? Unless the five players on the field share a brain, they feel that they want to be packed, and if they want to be marked, they can switch freely. But it turns out that something like Collins's will not work. ”

Collins was the head coach of the Bulls that year, the famous tactical dictionary of the year, standing on the sidelines and shouting directly at the players what tactics to use, and the players listened to the command to change the formation, but the Bulls with Jordan played extremely rigid, and finally he was replaced by Jackson, the master of the "Wild Fox Zen" faction. The latter led the Bulls to great success.

Later, everyone talked more and more openly, and the ideas became wider and wider, but only Fox Leon, who only had a few words from beginning to end, and drew on the board from time to time, seemed to have fallen into this problem.

"Fox, don't get into the nitty-gritty, this question is about opening up ideas and exchanging experiences, not really trying to come up with an answer. Tell us what you think, but in the afternoon we are going to watch the video of this year's finals together. Gelgurich said by name, Leon.

Leon then came out of his thoughts, he cleared his throat, and said: "In 1940, when cryptographers were trying to decipher the German ciphers by using linguistics, semiotics, ciphertext, intertextuality and other methods, Alan Turing finally cracked those ciphertexts with a calculator he made, because there were a total of 159 billion possibilities for those ciphertext combinations. In 1976, at the University of Illinois, they used two electronic computers to design a program, spent 100 hours, tried 10 billion possibilities, and proved that the four-color conjecture was correct. I just spent 15 minutes estimating that if the two defenses are combined with each other, in different areas of the half, in the face of different offensive situations, fuzzy calculations are used - here with a little knowledge of membership functions, there are about 1280 possible situations. If we summarize the classification, we can roughly summarize it into 19 categories. If, I mean, as Carlisle said, the players on the field share the same brain, and are familiar with these 19 types of situations, they can probably switch between those two defensive modes with ease. “

After Leon finished saying this, he saw the other five people looking at him blankly, and then looked at each other at the people sitting next to him, revealing the expressions of elementary school students listening to high mathematics. Finally, Gelguric spoke: "What kind of fellow is this, freak, or ...... Genius ......" (To be continued.) )
