Many times, sports have been at the leading edge of data analytics. The book “Moneyball” was one of the first popular books to bring the basic concepts behind data analytics and data science to the general audience. Fantasy leagues, sabermetrics and even games like “Strat-O-Matic” baseball and basketball provided an introduction into basic statistical concepts.
And it now seems that sports, in this case the National Basketball Association (NBA), are breaking new ground with another data analytics topic: who owns the data? The National Basketball Players Association recently banned NBA teams from using a player’s wearable data in contract negotiations or other transactions (see “NBA Bans Teams From Using Wearable Data In Contract Negotiations”).
Maybe after the bitter fights professional and college athletes had about their “likeness” being used for advertising and promotions (think College Hoops 2K8), the players association wanted to get ahead of the curve on the data ownership issue. If that’s the case, then that’s a very smart move – and a very telling move. It brings to light a very interesting question: who owns the personal data coming off wearables and other “intelligent” devices, and when and how can that personal data be used?
It’s easy to imagine how the NBA owners, agents and coaches could use the wearables data. But there is already a plethora of data available on player performance. Do I really need wearables data to tell me that Carmelo Anthony (over-rated New York Knicks forward) doesn’t hustle back on defense (or maybe even play defense)? I can just look at some basic statistics to uncover that insight (see Table 1)
Offensive Real Plus-Minus
Defensive Real Plus-Minus
|Carmelo Anthony, New York Knicks||2.18||-1.84|
|League Rank||#35 out of 445||#403 out of 445|
Table 1: Source: http://www.espn.com/nba/statistics/rpm/_/sort/ORPM
From Table 1, we can see that Carmelo Anthony ranks #35 out of 445 NBA players for offensive effectiveness; however, he only ranks #403 out of 445 players on defensive effectiveness. Again, I don’t need to see wearables data to understand where during the game Carmelo Anthony is putting his effort and hustle. Plus there are other ways to get much of the same performance and effort data, such as video analytics.
Wearables data could be very beneficial to teams and players by scientifically flagging when a player is gassed and needs a rest, or whose body might be breaking down and needs to take a game off. Wearables data could be used to create personalized training programs that optimize an individual athlete’s strength, endurance and agility capabilities. Wearables data could be used to minimize training injuries and speed injury recovery. The number of ways that wearables data, especially combined with in-game performance numbers and other external sources such as weather (temperatures, humidity, precipitation), social media and location data, could improve individual athlete as well as team performance is only being scratched.

So Who Owns the Nest Data?
Just imagine all the insights that Google Nest could glean from having sensors placed throughout your house. Here are just a few examples of the types of insights that Nest could glean from that data:
- How many people live in the house?
- When those people are typically home during the week?
- When those people are typically home during the weekend or holidays?
- When do they typically go to bed?
- When do they typically get up in the morning?
- Is there movement during the sleep period and if so, when and where is that movement?
- When are the residents on vacation? When do they typically go on vacation? How long are they typically gone while on vacation?
- Do they take weekends away from the home (like ski weekends) and does that correlate to any holidays or
- Does the time away from the home correlate to turning down the heat?
- And more!

Okay, so not much comfort here that my personal data is being protected and won’t be used for whatever purpose Google decides. But here is what I found even more concerning, selecting the “See our Privacy Statement for Nest Products and Services” link took me right back to this statement. Yea, a circular reference to a privacy statement that says nothing about how they are going to protect your information. If you have a Nest device and are not concerned, well I got a bridge in San Francisco to sell you…
And that should scare you.
 Real Plus-Minus (RPM) Real Plus-Minus is meant to be predictive. RPM can help coaches (and agents) differentiate between players who have been consistently good (and will likely keep being good) and players who are merely going through a hot streak (and will likely regress to their mean).
