millionary betting market that uses the countless statistical data generated after each game to feed the wagers This leads to the existence of a rich historical database that motivates us to discover implicit knowledge in it In this paper we use plex work statistics to analyze the NBA database in order to create models to represent the behavior of teams in the NBA Results of plex workbased models are pared with box score statistics such as points rebounds and assists per game We show the box score statistics play a significant role for only a small fraction of the players in the league We then propose new models for predicting a team success based on plex work metrics such as clustering coefficient and node degree Complex workbased models present good results when pared to box score statistics which underscore the importance of capturing work relationships in a munity such as the NBA Categories and Subject Descriptors H28 [Information Systems] database management Database

founded in 1946 and since then is well known for its efficient anization and for its high level athletes After each game played a large amount of statistical data are generated describing the performance of each player who played in the match These statistics are used in the United States to move a betting market estimated in tens of billions Permission to make digital or hard copies of

USA Copyright 2021 ACM 97816055819340808 500 of dollars In 2021 the Nevada State Gaming Control Board reported 24 billion in legal sports wager [10] Meanwhile in 1999 the National Gambling Impact Study Commission reported to Congress that more than 380 billion is illegally wagered on sports in the United States every year [10] The generated statistics are used for instance by many Inter sites to aid gamblers giving them more reliable predictions on the oute of uping games The statistics are also used to characterize the performance of each player over time dictating their salaries and the duration of their contracts Kevin Gart [18] averaged 224 Points Per Game PPG 128 Rebounds Per Game RPG and 41 Assists Per Game APG in the 20212021 season making his salary to be the highest in the 20212021 season 2375 million On the other hand Anderson Varej ao [18] who had 60 PPG 60 RPG and 06 APG in the 20212021 season asked in the following season for a 60 million contract for six years and had his request neglected Robert Horry [18] who is at the 7th position in the rank of players who won more NBA championships with seven titles for three different teams has career averages of 72 PPG 49 RPG and 22 APG and in the year 2021 of his last title had a salary of 3315 million Two simple questions arise from these observations First would Anderson Varejao be overpaid in case his request were accepted Second is Robert Horry underpaid once he wins a title for every team he played The first question was answered by Henry Abbot a Senior Writer of ESPN in his blog True Hoop [1] He said PPG RPG and APG only measure the actions of a player within a second or two when someone shoots the ball The rest of the time points and rebounds measure nothing He also said answering to the first question that these statistics are against Anderson Varejao who is one of the best players in the NBA in the adjusted plusminus statistic The plusminus statistic keeps track of the changes in score when a given player is either on or off the court and it does not depend on to box scores such as PPG APG and RPG [2 14] This indicates that Anderson Varejao could have asked for a 60 million contract Moreover in the aid of Anderson Varejao we point out that after he finally reached an agreement with the Cavaliers the performance of the team went from 9 wins and 11 losses to 15 wins and 7 losses with Anderson Varejao scoring 78 PPG 85 RPG and 12 APG before his injury For the second question we could not find an answer Robert Horry has played 14 seasons averaging a title per two years played and per team played Is he a lucky guy who always play with the best ones or he really makes a difference One thing we know for sure is that simple statistics such as PPG RPG and APG should not be the only metrics used to predict a player and team success While the statistics are treated separately and the players are treated individually little is known whether there is any relationship between them We have seen in history players with insignificant box scores statistics playing significant roles on a team success A possible way to study the collective behavior of social agents is to apply the theory of plex works [19 22]
