It wouldn't be done in blocks since they won't need to change it. Doing it in blocks at MetLife is due to the weight of the turf when changing it out. Can't just roll it up. Looking at the pic above with the unfinished turf in the dome, it looks like the endzones are in place and will remain green with either stitched in lettering or painted lettering. Hope I'm wrong. I'd love to have the gold Super Bowl endzone.
