Lightning is pretty amazingly serious and dangerous stuff. A cancellation, not a postponement, is pretty wild, though.
I don't even begin to pretend to know the decision making process which led to a cancellation, but I imagine that the choice to cancel, not postpone, was based on pretty careful assessment of the forecast, the use of the stadium, the logistics of resuming play at a later time, and the legal ramifications in having to deal with sponsors, fans, and universities following a cancellation.
But it is ironic, and amusing in a twisted way!
I was reminded of a 1980s Providence (RI) Journal newspaper report of a big Amtrak wreck, with fatalities, printed on the same page as a huge "Ride the rails with Amtrak" advertisement. It was a tragedy, of course, but there was twisted humor in that juxtaposition.
