It is curiously defeatist for someone who works in analytics to say that we'll just have too much data we won't know what to do with it.
There will be more data available, no doubt. It's going to get more complex, but so will our tools to make sense of it. And people who can make sense of it - and in doing so, differentiate themselves from those unqualified people that you are referring to - are going to do very well for themselves and ascend to more prominent positions.
If players celebrate their teammates' successes more frequently because they are being measured...isn't that validation of the approach? Measurement would have had the desired affect. You can argue maybe the celebrations become "artificial", but smart people will come up with workarounds. You can randomize rewards for celebrations to diminish the incentive to "fake" a celebration. You can rotate measurement among position groups, so that players don't always assume they are being measured. And eventually once the culture is in place you can do away with measurement altogether - and randomly bring it back for a week or two whenever you feel it's trending in the wrong direction.
FYI, I work at a data analytics company too. One of our investors is the owner of a Big 4 professional sports team that has won multiple championships this decade. Analytics are everywhere and only increasing.
