Or they play in an empty stadium-like practice.
My thinking is that
IF there's a football season (be it college, US pro, Canadian pro) you are correct,
Lawman.
But the only way this works is if everyone in the stadia are vetted and those who wish to participate have to sign a "hold harmless" agreement. Those who wish not to participate should not be penalized as well.
Vetted = proper quarantine period in which the person is determined not to have COVID-19, is not a carrier of it, or has already had it and cannot give it to others.
Those who have not had COVID-19 and are not carriers will have to live in a "bubble" with same.
Everyone = players, coaches, officials, and other support staff. And probably the broadcast crews too.
Is the above doable? Perhaps. Is it worth going through the logistics of all of this to have a season? That's a question only the schools, conferences, and the NFL and CFL can answer.
Since baseball is less of a contact sport that football, basketball, and hockey (what about soccer), I can see baseball perhaps restarting earlier than the others.
