Its amazing if they ripped the good stuff out of there and put the field turf in ....in a timely manner like they do. I've always been intrigued by the whole process.
Interesting. The announcers said the Raiders play on grass but they don't allow anybody else to play on the grass. So they use field turf for all non-Raiders games.
The grass is the Raiders and they just roll it outside when their isn't a game so it can stay in good shape. They don't want others using it ans destroying it. Here's a video of them rolling it in.
