Absolutely nothing.
Show me a basketball stat and I show you it´s fallacy.
The idea that we can use abstract placeholders to describe dynamic processes is theoretically feasible, but practically useless.
Games aren´t played in a vacuum.
How do you quantify experience, chemistry, KG´s will to win or the effect on your motivation a series of wins or losses have?
The only reason stats have entered basketball discussions is to have a "killer argument" if you want to justify why Player A is better or worse than Player B.
So, basically, it´s just media talk.
