Seems to me it should be taken out of the dictionary in today's world. Players seem to do what ever they want as long as it is not murder, assault on a women, or very nasty racial abuse no one cares Just saying . Rex taking responsibility for his players is what he thought he should do. Leaves the players to do as they please. Showing up late for meetings missed assignments on the field are probably only the tip of the iceberg.
Our whole society is losing accountability in my opinion.
