If you're a basketball fan,
-
you know your team's big stars, head coach,
-
maybe even the rookie bench warmers.
-
But you probably know very little
-
about the Ph.D. mathematicians like this woman.
-
Her job is to crunch the numbers of the game.
-
We're all in sort of an arm's race to acquire information.
-
And she's turning basketball
-
into a hard, cold science.
-
My name is Ivana Seric and I'm a data scientist.
-
For many years, Philly was a tough place
-
to be a basketball fan.
-
But having reached the top eight
-
in the playoffs for a second season in a row,
-
the 76ers right now are in a renaissance.
-
Embiid fakes, Embiid down the lane.
-
Just across the river
-
is where the team's been hard at work
-
and it's where I went to go meet Ivana in April.
-
This 125,000 square foot facility
-
comes with all the features you'd expect
-
from an NBA training complex.
-
It also features the office of people like Ivana
-
who support the team behind the scenes.
-
My job involves analyzing the data
-
that we have from NBA games.
-
My focus is mostly on the coaching strategy.
-
Coaches have a lot of intuition.
-
They know the game, they know the players,
-
but we try to complete their picture of the players
-
with data, which is hopefully unbiased.
-
Ivana is part of the Sixers
-
10-person analytics team.
-
The work of these statisticians has already forced
-
a profound change in the game of basketball.
-
Teams are taking more three point shots.
-
Embiid for three.
-
Even though we make them at lower percentage
-
than the shots closer to the basket,
-
but they're worth more points
-
and the trade off actually pays off.
-
Take a look at this clip from the '80's.
-
See how all the players are bunched up right by the hoop?
-
Compare that with today.
-
More and more of the action is
-
taking place at the three point line.
-
Of course, it's not just basketball
-
that's been reshaped by analytics.
-
Businesses of all kinds are tracking a ton of information
-
they never tracked before thanks to new sensors,
-
improvements in computing power,
-
implementing cost and data storage.
-
Data scientists are the people
-
making sense of that information
-
with a combination of statistics and computer programming.
-
The profession's expanded rapidly in recent years
-
and comes with an average salary of $130,000 a year.
-
Much of the data Ivana works with comes from
-
technology the NBA adopted in 2013.
-
Every NBA arena has cameras that record the games
-
and then from those cameras, they can
-
extract player locations on a court.
-
These cameras record 25 frames per second,
-
so for each basketball game,
-
there's a million of throes of data.
-
And that allows Ivana to analyze plays
-
that were previously difficult to track.
-
For example, take the pick and roll.
-
It's one of the most important plays in basketball.
-
It involves one player setting up a human shield
-
to help a teammate shake off an opponent.
-
So we can look at each player,
-
how much they run pick and rolls
-
and how good they are at that
-
and then we can select a player and see
-
how often he's going to pass out of the pick and roll,
-
how often he's going to shoot.
-
And how would that help you
-
develop a strategy for the coaches?
-
So we could, for example this player,
-
he's going to pass pretty frequently.
-
We can say this to the coaches
-
and they're going to decide on the
-
defensive strategy for the player.
-
But this makes Ivana's job
-
look simpler than it actually is
-
because she spends a lot of her time
-
coding to extract the information she needs.
-
And I tried really hard to get her to talk about
-
what exactly she looks for.
-
And there's some stuff that you do
-
that's beyond just these interfaces
-
that you showed me today, right?
-
Yep.
-
Can you tell me more about that?
-
Um, not really.
-
So that's like a trade secret?
-
Yes.
-
NBA's a very competitive league,
-
so whatever can give us that advantage, we try to keep it.
-
When advising the coaches with her analysis,
-
Ivana has a decided advantage over many of her peers.
-
I started playing when I was seven years old
-
and I just loved it from the first day.
-
I think 'cause the game is so dynamic
-
and there's so many different skills.
-
It's what I wanted to do since
-
I was seven years old, really.
-
I wanted to be a professional basketball player.
-
Yeah.
-
At 19, Ivana moved from her home in Croatia
-
to New Jersey to go to college on a basketball scholarship.
-
And while she was a star player on her Division I team,
-
she was also an exceptional math student.
-
Much of her life has been like that,
-
balancing her love of basketball with her love of math.
-
I always thought I'm going to have to
-
choose between the two.
-
I went to graduate school and that's when
-
I really thought that, okay, I'm really choosing
-
one or the other this time.
-
So I thought I really chose just math.
-
The plan was to become a researcher or a professor.
-
Then, three years into pursuing her Ph.D. in math,
-
she heard that NBA teams were starting to hire
-
data scientists, but only 26% of data scientists are women
-
and Ivana didn't like her odds.
-
When I saw the job posting,
-
I didn't think I would actually get the job.
-
I thought because being a woman
-
in such a male dominated field,
-
they would never really consider me or give me a fair shot.
-
But this prediction turned out to be wrong.
-
She's got both the technical and basketball backgrounds,
-
which is sort of the ideal mix.
-
Her ability to capture these complex insights
-
and then share them with players or coaches,
-
with executives in a way that makes sense to us
-
is super valuable and frankly, not that common.
-
The next evening,
-
I attended my very first NBA game.
-
It was the last game of the regular season
-
before the playoffs and my chance to catch up
-
with the ultimate beneficiary of Ivana's work,
-
the Sixers head coach, Brett Brown.
-
The team has had a great season so far.
-
What role do you think analytics has played in that success?
-
I think it's played a significant role
-
in our success and many, many others.
-
The NBA playoffs are going to start in three or four days
-
and immediately, we'll get an analytical assessment
-
on the strengths or weaknesses of an opponent.
-
You can assess play calls, good or bad ones,
-
ones you should do more, ones you should avoid.
-
Really, I think it's going to continue to grow
-
and play a significant role in the design of organizations
-
and coaching staff's beliefs.
-
That night, even though none of the starting players
-
played in the game, the Sixers ended up crushing the Bulls.
-
A month later, the Sixers ended up advancing
-
to the conference semi-finals and suffered a
-
tough defeat at the hands of the Toronto Raptors.
-
Is this the tie breaker?
-
Ivana and her colleagues
-
will keep looking for ways to help their team
-
do better in the seasons ahead.
-
But the Sixers victories on the court
-
won't be the only way she's measuring her success.
-
It's really exciting to be able to
-
show young girls that they can actually have careers,
-
but it also feels like a big responsibility
-
because if I don't do well,
-
it's going to seem like
-
a woman cannot do this job,
-
because there are not so many of us.
-
It's a big part of what motivates me every day
-
to be able to show young girls
-
that they can succeed in STEM fields and in sports.
