标 题: 关于NBA的走步规则和我们理解的三步上篮
发信站: 水木社区 (Tue Jun 4 09:00:47 2013), 站内
昨天,版上对LBJ的走步进行了一番争论,版内的很多篮球爱好者也给予了指点,
在此感谢。
在昨日的争论过程中发生了一些不文明行为,由于爱好和支持球队不同,某些人对
个人进行人身攻击。作为球龄超过20年老球迷,我由衷的鄙视这些人。
看球打球很多年,都是用平时打球的习惯思维来理解NBA的规则,因此难免在理解
和判断上存在偏颇。还请原谅。
昨日版内某位爱好者建议研究一下NBA rules 并贴出了07-08赛季的NBA rules,为
了谨慎起见,本人从NBA官网下载了OFFICIAL RULES OF THE NATIONAL BASKETBALL
ASSOCIATION(2012-2013)并对部分章节做了初步解读。得出了几个结论:
1、几个版本的NBA rules都没有三步上篮这个说法,也就是通常意义上我们理解的
The three step layup(有人将三步上篮翻译成Lay-up shot /Running jump shot
/Dribble shot)。2009年10月份,NBA rules 用“two steps”替换了“two-count
rhythm”,对这种说法,官方声明为:The section of the NBA rulebook dealing
with traveling used to allow players to "use a two-count rhythm in coming to
a stop." It was reworded this season to say players "may take two steps in
coming to a stop, passing or shooting the ball."
2、NBA rules(2012-2013)对走步、运球、轴心脚有很详细的解释(具体见下原
文)。NBA rules(2012-2013)中明确了“A player who receives the ball while
he is progressing or upon completion of a dribble,may take two steps in
coming to a stop, passing or shooting the ball.”
3、国内、国外包括NBA对走步的理解存在很多争议。2009年10月份,NBA对
traveling rule做了声明《NBA clarifies update -- not change -- to traveling
rule》(声明见下文)。ESPN亦对其进行了报道(有两篇报道值得一读,第
一篇是《NBA to alter traveling rules》,第二篇是《NBA Traveling: A Rule
That's Unclear to Players》。
一、OFFICIAL RULES OF THE NATIONAL BASKETBALL ASSOCIATION(2012-2013)部分节
选
RULE NO. 4—DEFINITIONS
Section VII—Pivot
a. A pivot takes place when a player, who is holding the ball, steps once or
more than once in any direction with the same foot, with the other foot
(pivot foot) in contact with the floor.
b. If the player wishes to dribble after a pivot, the ball must be out of
his hand before the pivot foot is raised off the floor. If the player raises
his pivot off the floor, he must pass or attempt a field goal before the
foot is returned to the floor.
If he fails to follow these guidelines, he has committed a traveling
violation.
Section VIII—Traveling
Traveling is progressing in any direction while in possession of the ball,
which is in
excess of prescribed limits as noted in Rule 4—Section VII and Rule 10—
Section XIII.
RULE NO. 10—VIOLATIONS AND PENALTIES
Section II—Dribble
a. A player shall not run with the ball without dribbling it.
b. A player in control of a dribble who steps on or outside a boundary line,
even though not touching the ball while on or outside that boundary line,
shall not be allowed to return inbounds and continue his dribble. He may not
even be the first player to touch the ball after he has re-established a
position inbounds.
c. A player may not dribble a second time after he has voluntarily ended his
first dribble.
d. A player who is dribbling may not put any part of his hand under the ball
and (1) carry it from one point to another or (2) bring it to a pause and
then continue to dribble again.
e. A player may dribble a second time if he lost control of the ball because
of:
(1) A field goal attempt at his basket, provided the ball touches the
backboard or basket ring
(2) An opponent touching the ball
(3) A pass or fumble which touches his backboard, basket ring or is touched
by another player.
PENALTY: Loss of ball. Ball is awarded to the opposing team at the sideline
nearest the spot of the violation but no nearer the baseline than the foul
line extended.
Section XIII—Traveling
a. A player who receives the ball while standing still may pivot, using
either foot as the pivot foot.
b. A player who receives the ball while he is progressing or upon completion
of a dribble,may take two steps in coming to a stop, passing or shooting the
ball. A player who receives the ball while he is progressing must release
the ball to start his dribble before his second step.
The first step occurs when a foot, or both feet, touch the floor after
gaining control of the ball.
The second step occurs after the first step when the other foot touches the
floor, or both feet touch the floor simultaneously.
A player who comes to a stop on step one when both feet are on the floor or
touch the floor simultaneously may pivot using either foot as his pivot. If
he jumps with both feet he must release the ball before either foot touches
the floor.
A player who lands with one foot first may only pivot using that foot.
A progressing player who jumps off one foot on the first step may land with
both feet simultaneously for the second step. In this situation, the player
may not pivot with either foot and if one or both feet leave the floor the
ball must be released before either returns to the floor.
c. 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.
d. 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.
e. A player who falls to the floor while holding the ball, or while coming
to a stop, may not gain an advantage by sliding.
f. 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.
g. A player may not be the first to touch his own pass unless the ball
touches his backboard,basket ring or another player.
h. Upon ending his dribble or gaining control of the ball, a player may not
touch the floor consecutively with the same foot (hop).
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.
二、NBA clarifies update -- not change -- to traveling rule
http://www.nba.com/2009/news/10/23/traveling.rule.ap/index.html
Posted Oct 23 2009 6:00PM
NEW YORK (AP) -- The correct call: The NBA has not changed the traveling
rule.
Stu Jackson, the league's executive vice president of basketball operations,
said recent media reports that the rule had been changed to allow an extra
step after the dribble were not true.
"We have not changed the traveling rule, nor how we enforce the rule,"
Jackson said Friday during the league's annual preseason conference call.
"What we did change was some antiquated language in our existing rule as it
related to steps."
The section of the NBA rulebook dealing with traveling used to allow players
to "use a two-count rhythm in coming to a stop." It was reworded this season
to say players "may take two steps in coming to a stop, passing or shooting
the ball."
三、NBA to alter traveling rules
http://sports.espn.go.com/nba/news/story?id=4563546
Updated: October 16, 2009, 11:19 AM ET
ESPN.com news services
NBA players will be able to take two steps before they have to stop, pass or
shoot this season.
The NBA has put into writing a rule allowing players on the move to gather
the ball, after driving or catching it, and then take two steps. Throughout
NBA history, the rulebook said players could take one step.
The new rule reads, in part: "A player who receives the ball while he is
progressing or upon completion of a dribble, may take two steps in coming to
a stop, passing or shooting the ball."
It is believed to be the first time any league, at any level anywhere in the
world, has explicitly allowed two steps.
In March, NBA vice president of referee operations Joe Borgia told
TrueHoop's Henry Abbott that referees had long been instructed to ignore the
rulebook on this point and allow two steps.
On a conference call with reporters earlier this week, NBA executive vice
president of basketball operations Stu Jackson told Abbott: "Based on Joe's
comments, when you had a conversation with Joe, we did in fact tweak the
language on traveling in this year's book."
Enforcement of the one-step rule has been hit-or-miss at every level of
basketball. Archival footage shows NBA greats, from Magic Johnson and Pete
Maravich to Bob Cousy and Julius Erving, getting away with two steps.
Borgia, whose father was also an NBA official, said he cannot remember a
time when NBA referees did not allow two steps.
Others insist allowing two steps represents an NBA strategy to aid scorers
and make the league more exciting. Legendary point guard and current Knick
broadcaster Walt "Clyde" Frazier says the league relaxed traveling standards
some time ago to increase scoring.
"They go 20 feet to the hoop without dribbling one time," Frazier said.
"This is what they are getting away with nowadays. Some of them are so
obvious. You'll hear me on the broadcast saying 'That's a travel! Watch the
feet!' Wilt [Chamberlain] would have averaged 100 points a game if they had
let him do that.
"When guys couldn't put up points, about when they changed the hand-check
rule, they made things easier for scorers, because these players can't shoot
like we did," Frazier said. "Those few years when the Knicks were good [the
early 1990s] -- that wasn't pretty basketball."
Whether or not this will affect play on the court remains to be seen.
Referees have long been instructed to allow two steps and in interviews with
NBA players last season there was some confusion about the rule. But most
said they thought they were allowed to take two steps.

四、NBA Traveling: A Rule That's Unclear to Players
http://espn.go.com/blog/truehoop/post/_/id/6036/nba-traveling-a-rule-that-s-
unclear-to-players
The question is basic: If you're dribbling the ball in the NBA, and you pick
up your dribble ... how many steps can you take before you have broken the
traveling rules?
It's a fundamental part of the game. But I asked several NBA players, and
the answers were far from simple.
Step One: Ask Players
"From what I understand," says the Sixers' Louis Williams, "it's two steps,
after you pick the ball up."
"Three," says Blazer Rudy Fernandez. "Or two."
"Two steps ... that's what I'm assuming," says his teammate Jerryd Bayless.
"That's how I always played."
Another teammate, Channing Frye, says it's two-and-a-half steps.
Blazer Greg Oden says he thinks it's two steps, "but I've seen a couple of
three-steps not being called."
Three steps? Could that be so? Should it be called a travel if you take
three steps?
Sixer Reggie Evans has some clarity. "Three steps," he says. "That's a
travel, all day ... Elementary."
Step Two: Ask the Rulebook
I ask several players if they have ever seen the NBA's actual written rule
on traveling at the end of a dribble.
Nobody has. Would they like to see it? Yes, they would.
This rule occupies 58 lines of the NBA's official printed rulebook. It is
full of talk of "count one" and "count two."
It was clearly written some intention other than being easy to understand.
They have some reading to do.
And as you'll see, everyone finds the rule too confusing to embrace -- at
least in the short time I gave them while the camera was rolling.
And Jerryd Bayless quickly strikes to the heart of the matter: "This is the
rule," he says, "but what are the refs going to call?"
Smart question. It gets us away from all that legalese, and gets the
conversation back to an area where we all have at least a little expertise:
The things we have seen happen in basketball games all our lives.
That question also exposes another key issue: The referees don't call it the
way it is written anyway.
