求大神解答

讲得太模糊了

当然算！

回

我觉得看临场

还不算，如果球回到后场后首先被a队球员最先触及就是回场

这球a队就不能碰了················
现在球回后场三要素简单很多了········

只要b队员抢断时没有把球碰到后场，那就是回场

这球根据上面的文字是无法做出判断的，根本不知道那一队获得持球

A team in control of a live ball in the frontcourt has caused the ball to be illegally returned to their backcourt if a player of that team is the last to touch the ball in his frontcourt and the ball is then first touched by a player of that team.
规则原文里指出三点：1.前场控制球（control）2.进攻队前场最后触球（touch）3.后场第一个触球（touch）
