I think that it takes a disciplined approach to take balls out of play with a nice lead in a game but ALWAYS playing the score is very important. Sometimes a player needs to lose a number of games with the balls located down table before they fully understand the importance of protecting a lead. I expect to receive some comments reference how str8 some young players shoot and runout in one pocket (much easier to do when balls are located at foot of table than high on my side rail). In relating this to killer instinct this makes your opponent EARN the win if he comes from behind in the game.
