Real grass would just die. The Saints did install a real grass surface in the Dome once before, but it was a very pricey and time consuming option for a playing surface.
Allegedly the FieldTurf surface has been tested thoroughly and shows that there is much less stress to soft tissue and joints as compared to natural grass surfaces. They also compared how it affects players in weather conditions that would make the turf slippery like rain & snow.
I really don’t believe the artificial turf is the issue. The Saints may just be soft. Or very, very unlucky. :covri:
