The Whip of the God of Basketball

　　 For a whole day, Leon kept himself in the room. He called the front desk for lunch to deliver food. After eating, he lay down in bed and took a nap to recover the physical strength that he had consumed last night.

　　 Then he got busy again and evaluated all the rookies in the draft according to his standards.

　　 He carefully read the statistics of each rookie, hoping to find something helpful.

　　 This made Leon feel like he was back in the work of actuaries in the past when they played with numbers, but no matter how he fiddled with the data, he couldn't form a clear evaluation of them in his mind.

　　The reason is simple, the data is too crude.

"Scores, rebounds, assists, blocks, steals, turnovers... some look good, some are average, but the scout report evaluates the opposite. It seems that the data does not fully reflect their performance. However, this is not the data. There is a problem, but the data here is not enough, not comprehensive enough, not objective enough..." Leon thought to himself.

　　 Different rookies come from different teams, have different coaches and teammates, and also have different games and opponents. The same data may reflect completely different levels of players.

Although Leon is not proficient in basketball, he is proficient in numbers. He knows that when a set of data describes things that are contrary to human sensory intuition, in a few cases it is because human intuition is unreliable, and in more cases it is because of data. Not complete enough.

Obviously, a report that only lists the basic data of rookies is far from satisfying Leon’s needs. Leon’s purpose is very clear. Since he still lacks a perceptual understanding of basketball in terms of experience and intuition, he uses these cold data. Come and lay an objective and firm foundation for yourself.

　　 Thinking of this, Leon called Westland and asked him if he had more comprehensive data.

"Comprehensive data? How comprehensive?" Weissland asked on the phone. As the Celtics' technical director, his main task this year is to build a player database for the Celtics, who have never entered the league. The veterans who are about to retire are all within the collection range of Westland.

　　 "All the data of every rookie in every game in college, all." Leon emphasized.

　　 "All... well, I do have data on almost every rookie's game in college, but it hasn't been sorted out yet. If you want to see it, I can send it to you."

　　Weissland didn't know what Leon wanted to do. After hanging up the phone, he brought his laptop and a CD to Leon's room.

　　 As soon as he entered the room, Westland saw piles of player information and a lot of manuscript paper on the bed. Leon wrote many formulas on the manuscript paper.

"What is written on paper?" Weissland looked at these formulas and felt his head was big. Although he majored in computer at the University of Colorado and had a good mathematical foundation, it was clear that Leon was on paper. The formula written is not the direction of his main study.

"It's just some simple statistical formulas. Your stingy boss didn't even configure a computer for me. Fortunately, I'm quite used to calculating with a pen. This allows me to get closer to the essence of numbers." Leon bit his mouth. He held the pencil and said, this is the pencil on the bedside message board, which has been bald by him.

　　 "Okay, hand in the information I want." Leon continued.

Wesland took out the CD, Leon saw this round guy and really wanted to say "Long time no see", then Wesland plugged him into the laptop, which stored a lot of An Excel file, each file contains data records of a dozen players in each game in the university.

　　 Leon opened these files one by one, looked at the detailed data inside, and couldn't help asking: "How did you do it? Every data of each person is recorded in the record, which can simply constitute a world."

Hearing Leon’s words, Westland raised his eyebrows and said triumphantly: “Every university will record the performance of their players. I don’t always have to work hard to get the data recorded on paper. Then put them into categories and statistics, and put them in the table. Although I don’t know what they are for now, I think they will be useful someday."

　　 "No, not one day, but today." Leon said firmly.

　　……………………

　　 While Leon was bored in the room working hard with a bunch of data, Pitino was chatting and laughing with Chicago Tribune reporter KC-Johnson in the cafe opposite the Athletics Association Hotel.

　　 KC-Johnson is only an unknown reporter in the Chicago basketball reporter circle, but in the future he will be the pillar of the Chicago basketball news circle.

　　 This year, after the transition to NHL reporters was not successful, he returned to basketball journalism. In his first year since the beginning, he cherished every opportunity to get news.

Therefore, even if Rick Pitino has lost its glory and has become a sour carrot head that not many reporters are willing to pay attention to, Johnson still thinks that he can get something from this controversial and condemned Celtic coach. Unusual information.

　　 Because KC-Johnson is not interested in Pitino, but the Boston Celtics. This sensitive reporter can smell the scent of the rain from the Celtics.

In the interview, Johnson always consciously or unconsciously led the topic in the direction of Celtic internal construction and management changes, hoping to get some news from Pitino, especially the importance of Auerbach’s return to management. dynamic.

　　 But Pitino played Tai Chi, and he often covered the management's problems without leaving a trace. Immediately afterwards, the conversation changed and brought the topic back to the draft.

　　 But KC-Johnson really has no interest in this year's draft. The outside world generally thinks that this is a draft year, and there is no super newcomer to watch.

The two talked like this, and they brag about each other for more than two hours. In the end, Pitino had no thoughts. Although he hoped to disrupt the draft market in this interview, he can think about it carefully. , This rookie is really nothing to cheat, and instantly lost the mood to continue to play tricks.

　　 At the end of the interview, Pitino suddenly said to Johnson: "The main change in the team is that after losing Bennett, we have a new scout."

　　 "Scout? Who?" For Pitino's relief, Johnson felt that he had a chance, and immediately asked, hoping to hear the name of a great person.

"You won't know him. His name is Fox Leon, a...very good guy, a scout recommended by Auerbach, I think he will play a key role in the Celtics draft. "Pitino said solemnly.

　　 As for scouts, Johnson is not interested. Fans will always pay attention to stars, coaches and excellent managers. For scouts or something, just let them discover new stars in silence.

Johnson is interested in the attributive "Auerbach recommendation", which means that Auerbach has begun to re-join the Celtic management, and secondly, it means that this scout has some background and was able to get Auerbach's. recommend.

　　 However, Johnson really has never heard of the name Fox Leon. He never remembered such a person in the basketball circle.

Johnson wanted more information, but Pitino said goodbye to him and ended the interview, but before leaving, Pitino added: "Tomorrow you can interview him at the rookie training camp. I think he is really good. There must be a lot of amazing views."

　　 Long before entering the NBA circle, as an avid basketball fan, Westland realized that there is a genius in this world; after coming to the NBA, he has confirmed this idea. There are sports geniuses everywhere.

　　 But this time, in Room 4016 of the Athletics Association Hotel, he realized that there might be one more math wizard in the NBA circle.

"I have calculated that whether it is scoring, rebounding, steals or blocks, assists, there is a significant correlation with the team's wins and losses, whether it is t-test, independent sample t-test, or correlation analysis, all support this Viewpoint. Then, if we comprehensively consider the influence of each player's points, rebounds, assists, blocks, and steals on the team's victory, I used a stepwise regression analysis to see the contribution of different players to victory in different aspects. It’s not the same. Later, I tried to filter all the data using the main cause analysis to filter out the part that each player contributed the most to the team. In this way, I can see where the outstanding value of each player is. From here, I can see that the empirical analysis of some scout reports may be unreliable, such as Michael Reid...Of course, I am not sure... and the data is still not rich enough. I think not only is they needed The data also needs the data of teammates and opponents. In addition, the classification of data is not enough, and the description of player performance by pure technical statistics is not perfect. I think it needs to increase the dimension of description." Leon held him in his hand. The conclusion from the work in the afternoon, tell the general content of it to Westland.

　　 Leon looked very excited, UU reading www.uukａnshu. After com traveled to this time and space, he has always been very calm, even cold. But when he came into contact with the numbers, the pieces of data, like the body scent of a woman, constantly stimulated Leon.

　　 also stimulated Westland.

Weissland is not completely ignorant of statistics. He understands many of the concepts Leon said, but the problem is that these data are usually calculated directly with a computer. He has never seen a guy holding a The pen scribbles on the draft paper and calculates these complicated inspection results with the decimal point to the last four digits.

　　 Leon is the first one he has ever seen, using pen to calculate roots and do logarithms.

　　 As for the variables that are calculated by the four arithmetic operations such as the average, sum, or variance, Leon always takes a while and writes the results directly on paper.

　　 "Are you the little prince of mathematics?" Weissland stared at Leon for a while, and finally asked.

Leon just shook his head, still keeping his eyes on the pile of numbers. He said, "No, I just have a special talent for observation and calculation. I am sloppy in logical thinking, and abstract in mathematics. In terms of thinking and construction ability, I am only at the level of a junior high school student compared to a real mathematics genius. Therefore, I am better at statistics and technical calculations. I am not a little prince of mathematics... I think I need to split the score in this item. To score and refine, you must add the total score of the team, the opponent's score for weight, and..."

　　 Talking about it, Leon has entered his digital world again, but Weisland feels vaguely that this guy might bring something different to the basketball world.
