I have a tremendous history with coaches. It started by growing up with an NBA Coach of the Year living across the hall from me for my entire childhood.
That helped me grow up to have an 18-year NBA career playing for 15 different coaches. And when you consider that I had one coach (Doug Moe) for eight of those years, that means that I went through 14 coaches in the other 10 years. I was not a coach-killer, but it does show the life expectancy of a coach is about the same as a fruit fly.
