Simple Explanation to Machine Learning Ensemble concept

I have been always a fan of using analogies and learning examples instead of complicated statistics and math functions in order to understand a concept in Machine learning.

Team A has conceded 0 goals all seasons thus it is concluded that Team A has the best defense mechanism.
