Remember the Bad News Bears? It did not help them to get a pep talk at first.
What helped them was getting uniforms, which gave them dignity. What helped them was getting training and coaching, which gave them skills and self confidence. What helped them was getting gas money to travel to the games, which gave them access.
With all of these assets in place, it is now a great time to give them a pep talk. Now they will be able to appreciate it, absorb it, and use it for inspiration. Otherwise it would have just fallen on deaf hopeless ears.
Though the Bears fail to win the championship game, their story gains attention, and Walter Matthau is able to get a return on his investment as his reputation improves in the local sports community (maybe spring boarding him to a solid coaching position at a high school … who knows).
