I see it like this. He's played with the teammates he named for how long? On average let's say 5 to 6 seasons. Jaylen, who is a smart guy, likely uses his high sense of awareness to understand them through a subconscious scientific method. This internal process allows him to refine his communication over time:
- Forming a hypothesis based on observations.
- Testing that hypothesis through specific communication styles.
- Noting how the individual responds.
- Forming a conclusion.
Obviously, this is how any intelligent person learns effective communication. Astrology may simply provide the language to articulate what he has already learned through years of experience. If astrology were a perfect predictive tool, a person could communicate flawlessly with a total stranger without building any prior rapport. All they would need is their birth chart. IMO while astrology can be a helpful framework for some, it is often used to pre-judge others, which frequently leads to confirmation bias.
