"The only way I'd worry about the weather is if it snows on our side of the field and not theirs"

Tommy Lasorda's quote is a metaphor for competition. He is suggesting that the only time he would be concerned about the weather is if it affects the outcome of the game. He is implying that he is positive in his team's ability to carry out regardless of the weather condition, and that the only thing that would stress him is if the weather condition offers an unjust benefit to the opposing team. This quote talks to Lasorda's competitive spirit and his dedication to winning. He wants to do whatever it requires to ensure his group's success, even if it means stressing over the weather condition. Lasorda's quote is a pointer that success in sports is typically identified by factors outside of the players' control, which it is very important to be gotten ready for any scenario.
