" How does a cranky, demanding coach create the most cohesive team in all of sports?

This is a tempting explanation, because the Spurs clearly make a concerted effort to select high-character individuals. (Their scouting template includes a check box labeled “Not a Spur.” A check in this box means the player will not be pursued, no matter how talented he is.) "
