Ok, keeping a running tally of something and performing an analysis to determine if there is a statistical correlation between two things are completely different excercises. Since you don't know the difference I'll take that as you have no idea.
As a general rule, if the article just adds things up and provides a ranking, it likely isn't doing anything with any statistical significance. If they run regression and/or check for correlation and mention an r squared value, it is probably statistically relevant.
Here's an article that shows managers don't "consistently" do anything, meaning there is little correlation. It's the best one I could find with minimal searching:

And here's one that shows how going over/under the Pythagorean record is pretty random for those that don't understand what "R squared" means:
