interesting, i see his best skill in motivating others to believe that they can achieve. which seems 3w4 to me more than 1w9. i know a 1w9 so/sp infj who ultimately seems warmer and somewhat more down-to-earth than coach k. not as if that's a knock, bc coach k seems great at mobilizing people/talent and getting them to completely buy in to the group project. but he seems like he does it in a way that's less measured and deliberate than an infj and more extroverted, energetic, and taking the lead. like he's supplying the energy more than just shaping it or responding to it.
i could maybe see phil jackson as a 1w9. he's tough to pin down, tho intj seems well established. he seems so much more self-enclosed, amused, internally focused than coach k.
candylandjoe, i see 7 as more focused on excitement, enthusiasm, and especially novelty. 3 optimism is focused more on reward than potential, plans, etc. 3 mobilizes more completely, and it falls in love with the experience of performance, rising to meet challenges, etc. 7 falls in love with spontaneous energy, passion, excitement, the wealth of possibilities that emerge and how much meaning can congeal into one huge explosive force.
