Imagine the scenario where we do find or are clear on track to have an effective vaccine that can be administered to the masses in December/January (wishful thinking, I know, but this isn’t the point of this post). The powers that be see this coming and decide to push football to the spring so that fans can attend without worry so there is no money lost due to decreased or no attendance (which will almost assuredly happen no matter what if they play in the fall, so in some ways it makes financial sense to push the season back if you have a vaccine). January and February football at RES would be miserable weather-wise. I was a cast member of the opening ceremonies for the Olympics that were held in February, and that is the second coldest I have ever been in my life.
Now the strange point of my post…is there any way to put a temporary/removable covering over the stadium, like some sort of bubble (I know they exist on a much smaller scale). Something to keep in some of the heat and protect against some elements, but not a true dome or retractable roof. (Arrowhead stadium had a rolling roof concept at one point, but the estimated cost of that was $100 million). Not sure if it would economically feasible or even feasible on an engineering level.
