If you aren't a great leader leading a great team, you need to realize it. If you are a leader in name only, then you have to find the real leader or maybe accept team leadership. If your focus is clear enough, you may not even need a leader, the path may be set. The path leads you, not a person. The leader may articulate that vision but if he or she really has to lead us, then we are all in trouble.
Great teams stand up for each other.
If someone from the outside wants to call out a member of the team, the rest are ready to take some of the fall. They rise and they fall together. It isn't about getting all the glory nor is it about avoiding the fall. There is no shame in giving it all and failing. No is their any shame to accept the fact that someone on that team may have made a mistake and life goes on.
