The [best] coaches... know that the job is to win... know that they must be decisive, that they must phase people through their organizations, and at the same time they are sensitive to the feelings, loyalties, and emotions that people have toward one another. If you don't have these feelings, I do not know how you can lead anyone. I have spent many sleepless nights trying to figure out how I was going to phase out certain players for whom I had strong feelings, but that was my job. I wasn't hired to do anything but win.
