NBA will allow coach's challenges this summer
The NBA will implement a coach's challenge at the upcoming summer leagues and
anticipates using the rule during 2019-20 regular-season as part of a pilot
program, per a memo sent to teams this morning and obtained by ESPN.
NBA將會在今年的夏季聯盟實施挑戰制度，並且預計在19-20賽季進行實驗
Coaches will get one challenge per game, and they will lose it even if the
challenge is successful, according to the memo. They can use it to challenge
only called fouls; goaltending; basket interference; and plays when the ball
is knocked out of bounds, the memo says. The league has tested this version
of the challenge system in the G League over the last two seasons.
教練每場比賽有一次挑戰機會，即使挑戰成功也會喪失挑戰權，可以挑戰的項目僅限於
犯規吹判、妨礙中籃、籃上干擾以及界外球，這個制度已經在G-League實施兩季
Coaches must have a timeout remaining to use a challenge. The team must call
a timeout immediately after the event they would like to challenge, and the
coach must "twirl his/her index finger toward the referees" to signal for the
challenge, the memo states. If the challenge is successful, the team retains
the timeout it used to stop play. If the challenge is unsuccessful, they lose
that timeout.
要挑戰時球隊必須還有暫停，教練決定要挑戰的話立刻叫暫停，同時對著裁判旋轉食
指，暗示裁判要使用挑戰，挑戰成功暫停次數會保留，失敗則會損失
The crew chief among the referees will determine the outcome of challenges
involving called fouls. The NBA's Replay Center will decide all other
challenges. Any technical flagrant fouls that occur during or "immediately
after" the call being challenged will stand regardless of the outcome of the
challenge, the memo says.
犯規吹判的挑戰會由裁判長決定，其他則是交給重播中心，但挑戰過程中或挑戰後不久出
現的技術犯規，無論挑戰的結果，都會保留
Both the league office and the NBA's competition committee, composed of
coaches, front-office executives, and players, are recommending the league's
Board of Governors approve the rule for the 2019-20 season "on a trial
basis," the memo says.
包括聯盟辦公室以及競賽委員會都建議高層能在19-20賽季進行這項試驗
"We anticipate this rule will be in effect in in the NBA next season as part
of a one-year pilot program," the memo states.
"我們預期這項實驗在下季就能收到效果"
When the league and its teams discussed the challenge concept at the general
managers meetings in May in Chicago, there was some trepidation about
allowing coaches to challenge called fouls, per sources who spoke to ESPN.com
at the time. Backers of a more expansive challenge have apparently won that
argument for now. Coaches will not be able to challenge uncalled fouls. Any
attempt to expand the challenge rule into that area would result in a bigger,
and likely longer, fight, sources have said.
五月時聯盟和球隊就有討論挑戰權的概念，讓教練挑戰犯規吹判讓人有些不安，所以支持
挑戰權的代價必須提高的那些人贏得這場爭論，例如教練不能挑戰沒有吹判的犯規，任何
想要擴展挑戰權的規則都必須面對一場更長更大的抗爭
Approving the proposed challenge rule for use in the 2019-20 regular-season
would require support from two-thirds of the league's teams in a formal vote
of the Board of Governors. The league will submit it to a vote before the
full board on July 9th. "Based on the feedback we have received, we expect it
to be adopted," the memo says.
要在19-20年實施挑戰權必須超過2/3的隊伍同意，聯盟將會在7月9號投票，
"根據我們收到的回饋，我們期望這項規則會被採用"
大概翻一下，有翻得不好的地方儘管指教，明天有時間再修正
