I wouldn’t trust the players too much to have any idea about what is acceptable.
I abandoned a supply league game for player safety after the home team had dug drainage ditches across the pitch. In most areas these were ok when I checked them before the game, but I didn’t notice one area was really bad and the ground was really soft. A player sprinted across this area and his foot went into the ground to half way down his shin. He was lucky not to break his leg - game over at that point.
The away team had travelled 2 hours to get there and they hadn’t told me about the ditches until I got there, so I felt pressured into playing the game. If they’d told me earlier I’d have inspected in time to stop them travelling and wouldn’t have had to abandon.
Both managers and the players wanted to carry on, and offered to sign a waiver to say I wouldn’t be blamed if anyone broke their leg! No thanks! I’m going home.
When you inspect, do it on your own so you don’t get pressured into making a decision someone else wants. Wear boots to check the pitch - I keep some in the car for this reason. If you’re not sure, put on kit and boots and take a ball. Have a gentle jog on the pitch, and if that’s ok do a bit more until you’re running reasonably hard. Don’t start sprinting until you’re sure it’s ok. Check the ball moves easily round the danger areas. The players will want to play but they’ll soon get fed up if the ball keeps getting stuck and then the boots start flying and people get hurt.
Yesterday was a perfect day for football. The ground was slippery but perfectly playable and slide tackles were going in left and right and no danger to anyone. Unfortunately players think a wet pitch is always like this. If there’s too much water that great slide tackle becomes aqua planing out of control, which is when legs get broken.
