A bit more background on Aoki-san from an April 1, 2007 article:
What is your favorite NBA team and why?
The Minnesota Timberwolves are my favorite team because the (previous) head coach of the team, Dwane Casey, is my friend.
(Timberwolves Vice President of Basketball Operations Kevin McHale fired Casey on Jan. 23 after he posted a 53-69 record as the team's coach.)
Casey was the coach of the Japanese Enterprises team, and he was coaching a women's team in Japan.
Dwane Casey was a Seattle SuperSonics assistant coach and he really liked Japan.
Casey's team gave my team a clinic 10 years ago.
(While living in Japan for five years, Casey also coached with legendary Pete Newell on the Japan national team.)
Have you and Casey stayed friends for a long time?
I believe that Casey is my teacher as a basketball coach, and because I cannot speak English so much I cannot make contact using the phone, but still I believe he's my friend and also a teacher.
Casey remembers me, I believe.
Who is your favorite NBA player now?
Kobe Bryant, because he can score a lot, 50 points in every game. A player who can score is a very attractive player.
