Just Google the new bernabeau, it legitimately retracts and grows the grass underground below the stadium.

People like Jerry Jones will fight it. He likes turf. He argues that the safety aspect of real grass is ambiguous but I suspect that turf makes it easier for him to have large events like concerts without worrying about screwing up the field surface. Considering how stubborn he has been about the giant glass wall facing West, I can't imagine he gives up the fight about turf easily either.

I agree. The Miami grass farm was interesting to me. A football field is only 1.3 acres. Have a 40 acre grass farm nearby and you always have multiple fields ready to go. Plan all of your events to allow for replacement time if necessary. It's not like these teams don't have the money. Grass just looks so much better.

A typical NFL stadium is not going to have 40 acres available nearby for a grass farm.

Some of y'all don't remember the fiasco with NRG and their "replaceable" grass field

Hard Rock Stadium constantly changes its grass by pre-growing fields at its team-owned South Florida Sod Farm. The grass field is changed as often as every month, depending on the conditions. The favorable Florida climate makes this feasible.

and where is Buffalo gonna have grass field to replace every month from Dec - February

Also i've seen a bunch of slipping and footing issues in the world cups games played on these indoor grass fields
