have bought in, players who have taken on leadership roles, and players who aren't getting time they want not but behind their teammates (just go back and watch Stewart's reactions after every made basket the last 5 minutes of the game).
The instance you mention was huge especially in light of the previous blown leads this year. Now come tourney time in a close game the players know they can keep the ship righted against a really good opponent even without the coach telling them how.
Coaches that let players lead especially in the tense moments develop leaders.
