1. Los Angeles is available to play
As noted by Sam Farmer of the Los Angeles Times, by rule the NFL makes it clear that home teams playing in international series need to make their stadium available just in case the worst happens in which things fail to work out. In other words, since the option is there for the Rams and Chiefs to play in Los Angeles to avoid any risk playing on poor field conditions, this seems like a no brainer.
Forget all of the promoting that has taken place over the last couple of months when it comes to this meeting in Mexico City since at the end of the day, football fans in general are still going to witness quite a showdown between these two playoff contenders. Plus, when looking at all of the hype surrounding this battle between the Rams and Chiefs in recent weeks since each team only has one loss, Los Angeles deserves to play in front of their own fans to help give them an extra advantage in this one.
Knowing that the NFL has the option to move this game back to Los Angeles seems like it should be the easiest decision in the world to avoid any sort of headache that could come if they were to move forward in Mexico City. Fans that were supposed to travel to Mexico City may not like this decision, but maybe down the road with better planning, another opportunity will come to attend a future game.
