Absolutely nothing.
Show me a basketball stat and I show you itīs fallacy.
The idea that we can use abstract placeholders to describe dynamic processes is theoretically feasible, but practically useless.
Games arenīt played in a vacuum.
How do you quantify experience, chemistry, KGīs 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, itīs just media talk.
