Done it at half time. But, have done it at competitions when the band was fragile. They would get psyched out standing in the end zone and making false comparisons before their performance. So I would turn them around and talk with them about anything to distract them from their self defeating thoughts. Now they can make accurate comparisons and have developed the mindset that is the basis of our competitive philosophy so they no longer need to be distracted and enjoy watching the other band from the goal line.
