My coach always says to play smart when you play basketball. He wants us to look up and look for open players and to drive in to ruin the opposing defense. Our team listened to him and we won two game in a row. Playing smart also means to take care of the ball and not to throw the ball to the the opposing team when you are in pressure. If you team starts to play smart, you will see a difference in your team.
In Tale of Two Cities, Defarge is the leader of the group when he storms the Bastille. Before, he storms it, he and his wife planned out everything. He planned to go to 105 North tower to kill a man, and he even went so specific to name the cell number. Defarge played smart instead of searching every cell, he chose the cell he wanted and went after it.
