good igls absorb stress and pressure from their team mates and go bald
bad igls offload stress and pressure onto their team mates and their team mates go bald but they provide something of value in return
the best igls absorb stress and pressure but know how to vent it in a healthy way and don't go bald
the worst igls provide nothing of value and no one goes bald because neither the igl nor the men under his leadership care enough to be affected by stress and pressure

do with this knowledge what you will.
