猫三在帖子里已经说的很清楚了,这两个图的中枢脚都是在移动脚落地之后才抬起的,因此都是好球。
如果猫三说得有歧义倒也可以理解,好在猫三说很清楚。

再附上NBA走步条例吧:
Section XIV-Traveling
a. A player who receives the ball while standing still may pivot, using either foot as the pivot foot.
a.原地站立接球时可以利用中枢脚(任何一脚均可)旋转。
b. A player who receives the ball while he is progressing or upon completion of a dribble, may use a two-count rhythm in coming to a stop, passing or shooting the ball.
b.在前进或完成上篮动作的过程中接球,可以迈两步然后急停,接下来可以选择传球或投篮。
关于如何判断球员迈两步的规则如下:
The first count occurs:
第一步在如下情况中已经发生:
(1) As he receives the ball, if either foot is touching the floor at the time he receives it.
(1)球员接球时至少一只脚触地;
(2) As the foot touches the floor, or as both feet touch the floor simultane- ously after he receives the ball, if both feet are off the floor when he receives it.
(2)球员接球时双脚腾空,接到球后单脚着地或双脚同时着地。
The second occurs:
第二步规定如下:
(1) After the count of one when either foot touches the floor, or both feet touch the floor simultaneously.
(1)单脚着地或双脚同时着地后----
c. A player who comes to a stop on the count of one may pivot, using either foot as the pivot foot.
c.球员可在停下后利用中枢脚(任何一只脚均可充当中枢脚)在原地停留,这还算做一步。
d. A player who comes to a stop on the count of two, with one foot in advance of the other, may pivot using only the rear foot as the pivot foot.
d.如果球员停下时一脚在前,一脚在后,这时他只能以后脚作为中枢脚原地旋转,而且算作
两步。
e. A player who comes to a stop on the count of two, with neither foot in advance of the other, may use either foot as the pivot foot.
e.如果落地时两脚平行, 他可以选择任意一只脚作为中轴脚,但要算作两步。
f. In starting a dribble after (1) receiving the ball while standing still, or (2) coming to a legal stop, the ball must be out of the player's hand before the pivot foot is raised off the floor.
f.运球之前必须先看是否符合如下事实:
1)静止接球后开始运球;
2)接球之后合法停止,在中轴脚立地之前球必须先脱手。
g. If a player, with the ball in his possession, raises his pivot foot off the floor, he must pass or shoot before his pivot foot returns to the floor. If he drops the ball while in the air, he may not be the first to touch the ball.
拿球队员如果中轴脚离地,在中轴脚落下之前必须传出球或将球投出;如果在中轴脚落地前
出现球脱手的情况,他不能首先触球。(注:球被对方碰掉或打掉的情况除外)
h. A player who falls to the floor while holding the ball, or while coming to a stop, may not gain an advantage by sliding.
h.球员因为滑到而倒地或停住,如果他手上持球时,他将是被动一方。
i. A player who attempts a field goal may not be the first to touch the ball if it fails to touch the backboard, basket ring or another player.
i.如果某球员投篮后球没有碰到篮圈、篮板或别的队员身上,他将不能首先触球。
PENALTY: Loss of ball. The ball is awarded to the opposing team at the sideline, nearest spot of the violation but no nearer the baseline than the foul line extended.
处罚:球权转换后将在边线发球,发球点应距离违例的地点较近,但距底线的距离
不得比罚球线的延伸线更近。
