2017年版篮球规则
第76页 规则 D.1.3 有写明 循环赛同战绩的比较方式
If 2 or more teams have the same win-loss record of all games in the group,
the game(s) between these 2 or more teams shall decide on the classification.
If the 2 or more teams have the same win-loss record of the games between
them, further criteria will be applied in the following order:
Higher goal difference of the games between them.
Higher number of goals scored in the games between them.
Higher goal difference of all games in the group.
Higher number of goals scored in all games in the group.
If still tied before all games have been played in the group, tied teams
shall share the same ranking. If these criteria still cannot decide at the
end of the group phase, a draw shall decide on the final classification.
另外 D.1.4 则这样写
If at any level of these criteria one or more team(s) can be classified,
the procedure of D.1.3 shall be repeated from the beginning for all the
remaining teams not classified yet.

阿你要聊天了没

所以就是先比他们之间的得失分差？

对战分差->对战得分->总分差->总得分
