Where I live during the Rugby and Soccer seasons it's not uncommon for the 'normal' pitches to be unplayable due to consistent periods of rain.
A number of schools, and public facilities, near me have switched to plastic pitches for this reason. I'm not advocating for them but there is a rationale.
BTW it's not just that being very muddy makes it difficult to play on but that using the pitch in that state trashes the grass.
