"If a horse won't eat it, I don't want to play on it"

This quote by Richie Allen implies that he only wants to use the very best possible field, and is utilizing a horse's selective nature as a standard. To put it simply, if a horse is not willing to consume the lawn on a field, then that field must not be great enough for Richie to use. This highlights the significance of having high standards and pursuing excellence in all elements of life, even in apparently trivial matters such as the taste choices of a horse. It is a pointer to constantly push for the best and not settle for mediocrity.
