Sample comprised 84 playoffs between 16 teams of National Basketball Association (NBA) during 2012. Data were analyzed using methods including independent sample t-test, one-way ANOVA, and chi-square test with α coefficient set at .05. Results showed that the difference in offensive time was significant between score leads and lags (t=3.711, p<.05) but not between periods of play (F=1.024, p<.05); attaching time varied significantly by transition methods (t=-35.271, p<.05); quick offensive tempo were not related to game results but usually resulted in a higher field goal percentage (χ²=.99, p<.05、χ²=10.889, p<.05); moderate offensive tempo usually resulted in a higher rate of losses and a lower field goal percentage (χ²=9.959, p<.05、χ²=5.752, p<.05); slow offensive tempo led to wins but a lower field goal percentage (χ²=9.633, p<.05、χ²=47.642, p<.05). In further comparison, the data of fast offensive tempo and slow offensive tempo were combined for comparison with data of moderate offensive tempo. Results showed that the difference in offensive field goal percentage between the two groups was not significant (χ²=.590, p<.05). As to game results, the group with more discrete offensive time had a higher rate of wins (χ²=17.915, p<.05). Overall, score leads/lags and transition methods would affect offensive time, and offensive time was a factor affecting field goal percentage and game results.
