I prefer grass. I am still skeptical about injuries on turf, even though "they" say that is not a problem any more. I think "they" are probably the Turf Salesman of America Association.
Remember Kenyan Drakes horrific injury at Ole Miss on their turf? I noticed during the Egg Bowl the other night they have natural grass now.
Simple physics are at play. Natural grass will create a divot when there is excessive force through the athletes foot. Artificial turf doesn't create a divot, and that excessive force is absorbed by the athletes body. Not a good equation.
The data for the new turf says otherwise for major knee/leg injuries. Mostly because the cleat (most teams probably where different shoes) tends to plant/stick on natural surfaces moreso than the turf.
And that's actual real world playing data, and not just an analysis by the sales team.
It does look like crap though.
