Does anyone recall seeing so many college games delayed and teams and fans evacuated due to weather as much as it happens in today's game? I don't recall seeing it when I was a kid in the 80's.
I think everyone's being more cautious about a lot of things (concussions, weather, liability, etc.) that may have been "overlooked" in the past. Locally (NoVA), there have been several high school games postponed in recent years because of rain (no lightning).
