There is constant discussion in the NBA community regarding which players are
the most productive and contribute the most to their teams. Let's take a
critical look at this from a statistical analysis perspective.
There are almost as many player rating systems as there are players. However,
some are certainly better than others. This article will focus on some of the
best and most meaningful metrics that exist today, and use those measures to
rank the most efficient players in the NBA for 2006-07.
First, a primer on some of the more in-depth statistics that will be used
(the data used for these "non-traditional" stats courtesy of 82games.com).
PER - A metric developed by statistician John Hollinger, this statistic takes
all measurable NBA stats, carefully weights them, runs them through a complex
formula and comes up with a final value that represents a player's overall
efficiency.
Net PER - Taking the PER of a player, and subtracting the PER of the player
he was matched up against in each game. The final number gives us an
indication of how a player performed against his "opposite number" throughout
the season.
On/Off - This is also known as the +/- number. The statistic for each
individual player indicates the impact he has on his team when he is on the
floor. This is calculated by looking at team scoring when a particular player
is on and off the court.
So, without further ado, here are the most efficient players in the league
(2006-07 regular season). Let the countdown begin!
10. Gilbert Arenas, Washington Wizards
Points: 28.4 Rebounds: 4.6 Assists: 6.0 Net PER: +6.8 On/Off: +14.1
Agent Zero is far from a zero on the basketball floor. He fills the stat
sheet on a nightly basis, has a very solid Net PER, and a spectacular On/Off
number. The entire complexion of the game changes when Arenas is on the
court, and that earns him a spot on this list.
9. Tracy McGrady, Houston Rockets
Points: 24.6 Rebounds: 5.3 Assists: 6.5 Net PER: +13.2 On/Off: +7.8
Another player with a nice all-around game. His On/Off number can't match
that of Gilbert Arenas (although McGrady's is still very good), but he
outproduces his opponents by leaps and bounds - which more than makes up for
it.
8. Kobe Bryant, Los Angeles Lakers
Points: 31.6 Rebounds: 5.7 Assists: 5.4 Net PER: +14.3 On/Off: +7.6
Some may wonder why Kobe isn't higher on this list. His overall production is
certainly top-notch, but the Lakers don't suffer as much without him on the
floor as one might think. The Lakers a one-man team? I think not.
7. LeBron James, Cleveland Cavaliers
Points: 27.3 Rebounds: 6.7 Assists: 6.0 Net PER: +13.6 On/Off: +9.6
Yet another superstar who isn't at the top of this list. All his numbers are
outstanding: he produces well in many areas, his Net PER is excellent, and
his On/Off number is quite high. He is a tremendous player, but there just
happen to be six other players who were even more efficient than King James
last year.
6. Manu Ginobili, San Antonio Spurs
Points: 16.5 Rebounds: 4.4 Assists: 3.5 Net PER: +14.5 On/Off: +8.9
This might cause some readers to shake their heads in disbelief, but here is
the scoop. This analysis is all about production, how well you hold down your
opponent, and how much impact you have on your team's success. Being more
famous or doing more shoe commercials doesn't count for anything here.
5. Dwyane Wade, Miami Heat
Points: 27.4 Rebounds: 4.7 Assists: 7.5 Net PER: +17.3 On/Off: +6.2
I doubt anyone is surprised that Wade cracked the top five. His overall
statistics are gaudy, and he outproduces his opponents by a ridiculous amount
on a regular basis. The only thing that kept him from being even higher on
the list is that the Heat don't exactly fall apart when he is on the bench.
4. Yao Ming, Houston Rockets
Points: 25.0 Rebounds: 9.4 Assists: 2.0 Net PER: +17.0 On/Off: +6.7
Yao has become an efficient scoring machine, and his work on the boards is
perhaps underrated. His Net PER and On/Off values are so high, he was able to
edge Dwyane Wade for fourth place. This might calm some of the "haters" who
think Yao is an underachiever and not worthy of all the hype.
3. Kevin Garnett, Minnesota Timberwolves
Points: 22.4 Rebounds: 12.8 Assists: 4.1 Net PER: +12.7 On/Off: +15.0
Garnett was his usual self last season for the Wolves - an absolute monster.
Very high production...and much higher than the forwards around the league he
routinely abused. His On/Off value reinforces the point that he was amazingly
valuable to Minnesota when he was in the fray. Celtics fans far and wide are
hoping for much of the same this coming season!
2. Dirk Nowitzki, Dallas Mavericks
Points: 24.6 Rebounds: 8.9 Assists: 3.4 Net PER: +17.1 On/Off: +12.4
The reigning NBA MVP almost took this title as well, but fell just a little
short of another superstar frontcourt performer. Dirk's stats are clearly
stellar, and he is a critical component to the Dallas Mavericks and the
success they've had. This is one case where reputation and analysis see eye
to eye, but there is one player the big German could not quite overtake...
1. Tim Duncan, San Antonio Spurs
Points: 20.0 Rebounds: 10.6 Assists: 3.4 Net PER: +14.8 On/Off: +15.0
No big surprise, but Tim Duncan was statistically the most efficient player
in the NBA last season. Known for his strong fundamentals and consistency, he
was just as consistent here, posting near-identical marks for Net PER and
On/Off ratings. Tim Duncan outperforms his opponents and contributes to
winning to such a large degree, nobody else in the NBA can match him in these
two vital categories.
As you can see, this method of rating players yielded some solid results. The
top-rated player just won his fourth NBA championship, and the player who
finished a close second led the Dallas Mavericks to a 67-15 regular season
and took home the 2006-07 MVP trophy. There is plenty of debate about the use
of statistical analysis in sports, but objective and subjective information
can sometimes lead us to the same conclusions, and this study led us directly
to the best players in the game today.
其實看不太懂 什麼是PER??
只知道老大排第一 Manu第六@@"
