I'm currently watching a replay of the CONCACAF Gold Cup soccer final that was held today at SoFi.
The stadium laid down a grass field to help demonstrate its ability to do so in hopes of securing the FIFA World Cup final in a couple of years. FIFA demands grass fields for its World Cup sites.
In watching the broadcast, I'm noticing some very significant seams in the field. Commentators have also noted that some of the players have complained about the conditions.
I think that this is the first time that I've heard of/seen grass at the stadium. If Stan ever wanted to go in that direction in the future for the Rams, it appears that there is a lot of work to be done.
