Shira has some interesting stuff on Brain Typing:
Throughout the Celtics' predraft process, Jon "The Brain Doctor" Niednagel was omnipresent, unmistakable in his track suits, usually trailing slightly behind Danny Ainge. While the trade for Kevin Garnett did not hinge on the brain type of the 10-time All-Star, it probably crossed the mind of Ainge. For the record, Niednagel categorizes Garnett as ENFP (Extroverted, Intuitive, Feeling, Perceiving), a classification nicknamed "the Motivator" and in sports generally linked to gymnasts. In his book, "Your Key to Sports Success," Niednagel describes those with an ENFP brain type as "highly energetic, enthusiastic, charming, imaginative, improvisational; sees possibilities; spontaneous; easily bored with repetition; enjoys solving people's problems; catalyst, marketer." What does this all mean on the court for a brain type that also includes Yao Ming, David Robinson, Marcus Camby, Jerry Stackhouse, Chris Webber, and Chuck Person? "In hoops, they love to move, jump, shoot, and block shots," wrote Niednagel. "They perform with active grace and are well represented in the NBA." When describing how ENFPs respond to pressure, Niednagel adds, "ENFPs tend to become too hyper, playing out of control. Loving to jump, they'll bound into the air to make a move without first surveying the floor. This can lead to untimely turnovers. Relying upon Feelings as their prime decision-making function, they may make unwise choices, acting too hastily." Paul Pierce falls into the ISFP category (Introverted, Sensing, Feeling, Perceiving), which is characterized as displaying artistic, athletic, and graceful tendencies and being sensitive, impulsive, sympathetic, and freedom-loving. For those looking for clues about how Pierce and Garnett might coexist, consider that Tim Duncan was an ISFP and he won two championships beside ENFP Robinson.
