A common mistake among those who work in sport is spending a disproportional amount of time on "x's and o's" as compared to time spent learning about people.
Mike KrzyzewskiVisualize a wagon wheel as a complete team. A leader might be the hub of the wheel at the center. Now suppose the spokes are the connecting relationships the leader is building with people on the outer rim of the wheel. If the hub is removed, then the entire wheel collapses. In a situation like that, if a team loses the leader, the entire team collapses.
