Ahhh. I get what you're saying and can see some of the logic.
My only thoughts about how the fall sports could be different is that a school like Alabama makes SO much more money from a football season than an Ivy league school does. Money is a huge driving factor for a lot of these schools and conferences.
I think it may be easier for an Ivy League school to shut down its sports programs because they tend to not be the biggest money makers for them, which allows them to make the better decisions for their student athletes.
It'll be interesting to see if the Ivy League really is the "canary in the coal mine" and other conferences/leagues follow suit.
One day after the Ivy League cancelled the entire season, the Big 10 just cancelled their non-conference schedule, Pac 12 will be next, so again the Ivy League seems to be one step ahead of everyone a second time.
