This metaphor will probably fly over most people's head.

It makes perfect sense to me if you can imagine the progression of a beginner entering any sport

When you try to become more athletic do you shoot more free throws or run more passing routes ? Neither. Your goal is to build a strong foundation in strength, speed, agility, and power up to an elite level and then specialize once you've decided what sport or position you want to play to tailor your training appropriately.
