NFL needs to 'seriously' look into grass-turf debate

[Mackeyser]

So you are saying there is zero cushioning effect with artificial grass/turf?

Not at all. The cushioning for the most part is an improvement over the literal carpet they used to play on.

The issue isn’t cushioning, it’s the right level of failure of the grass roots. Too easy to fail and the grass is slippery like in the Super Bowl. Too little failure and cleats get stuck and joint injuries happen.

The biggest problem with artificial turf is that between a knee getting blown out or the turf failing and throwing a chunk of sod, it’s always gonna be the knee because it literally can’t throw a chunk of sod. Because artificial turf cannot fail in the way that grass does, all that is xtra load or torsion or torque is applied to bones and joints and ligaments…
