科学解析：欧文不可思议的速度

To get an insight look

让我们深入了解一下

and what makes Kyrie Irving one of the most dangerous ball handlers in the NBA

是什么让凯里欧文成为NBA中最具有威胁的持球进攻者之一

We brought out gears to the Cavs practice facility

我们带着设备来到骑士的训练场馆

and wired up this three-time NBA All-Star, with science

将设备安置在这位3次全明星球员身上

So, what do you think separates you from everybody else?

是什么让你的进攻与众不同？

Being able to accelerate off my first step going to the basket,

能够在第一步快速加速攻击篮筐

or being able to pull back for a jump shot.

也能够急停中投

Is what, kind of makes my game little bit unique

这让我的比赛风格非常独特，难以防守

After testing a series of moves

在测试了一组动作之后

data from our wireless motion tracking sensors reveals that

数据显示

 he is able to accelerate to roughly 12 miles per hour in just two strides

欧文只需要两步就能够加速到12英里每小时

And from the stand still at the three-point line

在三分线外

Kyrie can get to the rim in as little as 1.5 seconds

欧文从静止状态攻向篮筐只需要短短1.5秒

that’s about 15 percent faster than the typical NBA point guard.

这比普通的nba后卫要快百分之十五。

But, what really makes Kyrie so dangerous off the dribble

但是真正让欧文的运球如此危险的

dribble 球场中最基本的单词

is his innate understanding of the defenders’ mental chronometry, or the ability to process time

是他与生具来的对防守人心态的了解，已经时间把握的能力

Before crossover

在每次变相之前

Kyrie typically exposes the ball for about a quarter of second

欧文会先将球暴露0.25秒

because it takes about two tens of seconds to react a visual stimuli

因为防守人需要0.2秒的时间做出视觉反应

This ball movement gives defenders’ brain just enough time to process the beat

这种运球让防守者来不及反应

And as the defender shifts roughly 60 percent of weight on one foot

当防守人将身体百分之六十的重量移至身体的一只脚时

Kyrie swings the ball behind his back at after 21 miles per hour

欧文以小于等于21英里每小时的速度背后变向

hat’s about three times faster than the strike of a Cobra head

这比眼镜王蛇攻击的速度还要快三倍

This allows Kyrie in just 35 hundreds of second

这让欧文能够在0.35内

to create about 5 feet of separation from his defender

这让欧文能够在0.35内创造出5英尺的投篮空间

and this is one reason why

这也是为什么

during the regular season, Kyrie actually averaged more points per game off the drives

在常规赛期间，欧文的场均篮下得分

than Carmelo Anthony and Kevin Durant combined

比安东尼和杜兰特之和还要高

And possibly the greatest impact Kyrie has on the Cavs offense

然而欧文对骑士进攻帮助最大的是

is his ability to open the rest of the floor for his teammates

是他为其他队友创造空间的能力

 Compare to when he was off the court this season

对比他在场与不在场的数据

when he was on the floor

在场时

he Cavs shot almost 4 percentage points higher in the paint

骑士队能够在禁区中的命中率高了4个百分点

and nearly 8 percentage points higher on mid-range shots.

中距离命中率更是提高了8个百分点
