期末考提早交卷之後實在太無聊了...|||

Bill Bridges put this in the comments, but it is too good not to make its own
post.
這只是出現在Bill Bridges的評論中的一段話，
但不把它拿出來當成一篇真的是太浪費了。
(以下都是quote)

The accuracy required for a player to hit a mid-range jump shot, let alone 3
pointers is astounding. Consider this. The inside rim of the hoop is 18? in
diameter. The Ball is 9.54? in diameter. If the ball lands exactly in the
middle of the hoop, the distance between the skin of the ball and the hoop is
4.2?. Let’s assume that if the ball is more than 4.2? away from dead center
that the shot is more likely to miss than go in. 4.2? is not a lot of room
for error. Players cannot be so accurate by measuring their shots. Rather,
the accuracy comes from over 10,000 hours of repetition during which the shot
is generated not by intent, but by muscle memory.
一個球員的中距離命中率，姑且不論三分，是很驚人的。
籃框內緣的直徑也才18吋，球就有9.54吋耶。
如果球在正中央穿過的話，跟邊緣的距離就只有4.2吋。
也就是說球只要偏離個4.2吋可能就進不了了。
4.2吋實在不是一個有很大犯錯空間的距離。
球員不可能去實地測量他的投籃角度，
而是用超過一萬小時的訓練建立出肌肉記憶。        *參考之前Sasha的神奇罰球影片

Kobe’ problem is that while his muscles are making the same movements from
memory (honed, in his case by well in excess of 10,000 hours), the
splint/wrap is introducing volatility in the angle of the ball. Simply put,
movement is perfect, yet he misses. To compensate, Kobe must adjust the shot.
This adjustment completely negates the reliance on muscle memory. The shot is
now aimed and adjusted and invariably misses.
Kobe的問題是他依然用老方法去使用他的身體，
但他的傷跟繃帶都影響了他手上的結構跟出手的角度。
簡單來說，姿勢一百分，但沒進就零分。
他必須要去按照現在的狀態調整出手感覺，
也就是說要去抹殺以前累積的肌肉記憶，
因為現在他出手的球似乎就是不太想進籃框。

To be as successful as he was shortly after the injury, he must have adjusted
his grip rather than the motion. The grip + constant dimension and tension of
the splint allowed Kobe to maintain the same motion with good results. But
something has changed in the last few games and the shot is more volatile
than before. The wrap is different. Or the splint is stiffer. Or the pain is
such that Kobe cannot maintain an adjusted grip. Whatever the reason, the
volatility of the shot has increased. This must mean that more of his shots
are off- center. The more off-centered the shot is, the more likely it is to
miss.
受傷之後要立刻成為跟他以前一樣可怕的人，
他要調整的是他的握力而不是身體姿勢。
他必須調整手指上的力道、他本身的空間感跟繃帶的緊度。
但過去幾場他的狀態有點不穩定，
也許是繃帶彈性或是緊度不一樣、
也許他痛到無法控制指力。
不管怎樣，球不穩定是個事實。
這代表他的出手是偏離中心的，自然難以進球。

To refresh you of elementary trigonometry, let’s assume that that a direct
line from the shooter to the middle of the basket is the adjacent side of a
right triangle, the actual line from the shooter to the hoop is the
hypotenuse and the distance between the middle of the hoop and the actual
point of contact is the opposite length (or the “error”). (with me so
far?). Then we can calculate the error resulting from an incremental drift in
the angle of the shot from dead center when the shot reaches the hoop. If
this error is in excess of the aforementioned 4.2?, the shot is likely to
miss.
我們來複習一下三角幾何。
球員到籃框中心是直角三角型的斜邊，
但球的路徑是個拋物線，
進入角度的籃框寬度並不是原來的18吋，
所以我們可以來計算一下這誤差究竟有多大。
很明顯的，只要偏離的程度大於4.2吋(經過三角函數)的修正數值，
這顆球就不會進籃。

From 10 feet away (an ideal post-up turn around distance), a shot 1 degree
off dead-center results in an error of 2.1? – a make. A 20 footer, results
in an error of 4.2? – a 50/50 proposition. A three pointer of 24 feet
results in a 5? error – most likely a miss.
在理想的低位距離--10呎之外出手，
偏離一度的誤差是2.1吋...進。
20呎之外，誤差是4.2吋...50%。
24呎之外，誤差是5.0吋...籃板。

Now let’s assume Kobe’s shot is off center of 2 degrees. A 10 footer is off
by 4.2?. 20 footer is off by 8.4? – barely grazing the rim. A 3 pointer is
an air-ball.
現在我們來假設他偏了兩度。
10呎的誤差就是4.2吋，20呎就8.4了...幾乎碰不太到框。
三分球...就是個麵包了。

An error of 3 degrees turns even the 10 footer into a miss. Something has
resulted in more of Kobe’s shots being 2 – 3 degrees off center.
如果偏離三吋的話，10呎的跳投就不會進了。
而Kobe現在的狀況不只是兩到三度的微小誤差。

I’ve even ignored the increased velocity that long-distance shots require.
This serves to magnify the errors by increasing the kinetic energy of the
bouncing ball. The same error factor is more likely to result in a miss for a
long shot than a short shot.
我還沒把長距離投籃所需球速的因素計算進去。
這跟球的動能有關，會將球本身的誤差加得更大。
同樣的初始誤差，長距離的出手會比短距離的更難投進。

If the volatility introduced by the splint is going to linger and be
persistent, he has to change his approach.
如果指傷造成的不穩定會繼續持續的話，
他就必須要調整整體的狀況了。

- He needs to go back into the post and try to get more 10 footers than
continue shooting from the perimeter
他可能要回到低位去投更多10呎跳投而不是中長距離或外線。

- On the perimeter, he needs to shoot more bank shots, ala Duncan. A bank
shot serves to reduce the velocity and the net effect is akin to reducing the
distance of the shot. (Newtonians note, this is due to friction, a
frictionless system would have bank shots at the same level of accuracy as a
non-bank shot).
在中距離的出手他得學某佛投擦板。
擦板球會減緩球的速度，並且間接等同於減短了投籃距離。
這看起來不符合牛頓運動定律，
是因為摩擦力讓系統內的能量轉換成熱能...(他好像沒說這個我雞婆了)

He could also take a week or so off and, god forbid, let his finger heal a
bit.
或他也可以選擇去放個假休息手指，不過應該不太可能。

After the game last night, a reporter asked Kobe if it was crazy to think he
would take time off. “Probably” was the response.
比賽結束之後有記者問Kobe，
如果他猜測Kobe會放假的話是不是瘋了，
「搞不好喔，我看看你有沒有發燒」。

On another topic, Darius had these thoughts about Bynum getting touches and
being more active, and if that should continue when Gasol returns.
另外一方面，Darius在思考，
Bynum是否會，或是應該在Gasol回來之後繼續有現在這種表現。

Bynum is still a player that focuses (mostly) on how he can get his. This isn
’t necessarily a bad thing (I love that he *can* get his and has developed
into a pretty reliable post threat). But that (gunner-ish mentality) creates
a trickle down effect for how efficient our offense can be – because even if
Bynum plays at an efficient level (he does) what makes this offense elite is
creating easier opportunities for others based off your own efficiency (i.e.
drawing extra defenders and getting your ‘mates open shots).
Bynum到目前為止大致上還是個鈔票衝腦的球員，
這不是壞事啦，至少我很開心他真的拿到了該拿的那一份，
而且還真的變成一個滿有威脅性的低位球員。
但這也讓進攻端多了一個疑問。
即使Bynum一個人打得很有效率，
但湖人的系統是你得犧牲一咪咪自己的數字，
讓球隊整體的數字好看，
例如說幫隊友吸引包夾然後傳給他之類的。

So, in the end, while letting Bynum do his thing may get this team a more
engaged and active player, what is the tradeoff? Less touches for a just as
efficient (and even more helpful to his teammates) player in Gasol? Less easy
opportunities for our guards and wings because they’re creating shots for
themselves (like Farmar/WOW shooting pull up jumpers in the half court)
rather than our bigs creating shots for them? I mean, this is what I’m
seeing and while I’m not mad about it, I’m not ecstatic about the results
either.
所以呢，讓Bynum打他想打的球，
也許會在場上有個很棒的積極球員，
但負面效果就是傳導變少，
像Gasol這樣有效率的球員也許更難拿到球。
後衛們更難有拿下easy basket的機會或是空檔的出手，
他們就必須自 己 製 造 機 會，
例如那精美的魚神嫡傳Farmar快攻急停三分。
我是說，這是我看到的啦，
但反正我也沒在生氣，所以結果怎樣？
管他的。

穆托姆博的全名至今是個謎，據說光他的姓氏就有55個單詞，「穆托姆博」只是他家族姓
氏中的一部分，這還不包括他本人的名字。現在坊間最流行的一個版本稱穆托姆博的全名
是「Dikembe Mutombo Mpolondo Mukamba Jean-Jacque Wamutombo」，但這個名字並沒有
得到穆大叔本人的首肯。

推 spko:那兩段應該要這樣翻，從「On another topic」開始後的幾句：
→ szuta:沒去看前一段...不過基本上是差不多的意思,反正就那種心態
→ spko:另一方面，Darius在想，Bynum有了更多持球機會而變得更為積極

推 spko:最後一段也順便翻了：

→ spko:？外圍球員得到的簡單機會也變少了、更多機會要自己來創造﹝
