I mean, it's not like we're in the Astroturf days where it was basically thin green carpet over concrete. In the old Georgia Dome, they had really long blades of synthetic grass with tiny ground up rubber pellets in it to simulate dirt. It was supposed to feel and be as safe as real grass.
They're playing a collision sport, so unless they wanna play on giant fluffy mattresses, there's always going to be the danger of injury hitting the ground.
