Every generation knows better than their descendants. Fact!
For lots of reasons, games are cancelled far too readily for my liking. I found it intriguing across the same geographical area, my local grass roots league got three quarters of our games played, yet there was only two (from dozens) step 5 to 7 games that survive the same weather. Either my immediate colleagues were wrong to play, or it shows the forces acting upon referees at the next level up
In my experience playing, home groundsmen were always keen to 'protect the pitch' when we knew they had a weakened team that day
Grass always recovers, especially when tended to do so. Wet weather followed quickly by a very dry spell causes problems, but that's not our problem.
VAR, HB, Dissent, inclement weather, rub of the green.... What 'football expects' these days, is an exact science, but that's not what sport should be about
