If they could extend the grass a few yards past the endzone I feel like it would help but I have no idea how that would impact things. For the NEZ a short padded wall before you get to the band stands for players to brace themselves after running through the endzone. There have been occasions where players can't stop because it's slippery and they are running fast and have to run all the ways to the bleachers or hillside, and then fall lol.
Maybe I'm making something out of nothing but I think it would be nice to do something bring the field in closer to make it more intimate. Right now the endzones are like 20 yards away from the SEZ and NEZ bleachers and hillsides. Not much can be done about that now though. I'm just rambling at this point.
