At Dolphin's stadium they'll lay down huge rolls of sod before big games like the Super Bowl or the BCS. They are so large that they stay put. It's not the little squares that regular people get. If that isn't good enough there's some nice synthetic turf these days. Both options are cheaper than losing a star player.
Anyone remember that NFL exhibition game years ago in Mexico city at that stadium that holds like 200K fans? Might have been a bullfighting arena. I just remember that the turf was so loose it looked like a cow pasture by the end of the first quarter.
