When writing and making points about a subject, I tend to try and think of at least 3 things. This has absolutely nothing to do with anything spiritual. It is only because 2 only barely qualifies as a plurality - being only 1 greater than the singularity. A set of 3 of something gives rise to a (perceived) "proper" plurality. That's it, nothing more. I would guess it is the same with the basketball player. If you're going to bounce more than once... then twice is only barely committing to that plurality. 3 times is the perfect blend of plurality and brevity. What else does it need to be?
Everything you say may be true, but it may only be true of you and for all you know, God may have put that in your makeup.
Don't forget I called these thought trivia. Trivia is interesting, but usually not factual. However sometime trivia is the truth.
