The object of our research was to gain knowledge needed for the skills, tactics and game planning in basketball. We did this by considering the ways in which the rule revisions in 2004 of jump ball reduction and the implementation of APR (alternating position rule) affected the level of FGA (field goal attempts) and if it was related to the factors involved in the outcome of the game. We used all 56 matches of K university men's first division basketball league consisted of 8 school teams as the object of our study. The main results are listed below. 1. Through these rule revisions, there was no more difference in offensive possession due to jump balls. This brought about change in the factors involved in FGA levels. 2. We thought that in the number of offensive possessions, which is a factor in the levels in FGA, there would be an increase in the importance of offensive rebounds, but there was no significant difference. 3. We thought that during defense, which also is a factor in the levels in FGA, there would be a significant influence in: (1) possession through rebounding, (2) steals, (3) turnovers, and (4) free throw attempts as factors in the outcome of the game, more so than before. However, other than in possession through rebounding, there was no significant difference. 4. Even though jump balls were reduced and APR was introduced, we were able to reconfirm one of the important existing principals of the game: a higher number of successful field goals will be one factor in determining victory.
