I get your point and acknowledge that it’s somewhat tongue-in-cheek - but to clarify for the folks who have this opinion about cancellations - It’s not the people’s safety inside the stadium that’s the concern overall.
It’s that the fans and the hundreds of workers and support staff getting to and from that stadium in a potential severe weather situation.
It’s the same reason school gets cancelled due to icy roads. The school itself is just fine - you just might die trying to get to it.
