I see a delay here to start of practices, but not an altogether postponement of the season... I had heard rumblings that there was only going to be one scrimmage allowed which would be the preview.
Indefinitely does not mean that there won't be the chance for one...
If border state to Ohio also do similar things, I think that there is a good chance Ohio will allow for some type of season.
However, how schools handle an outbreak in their community or positive cases on their team will be a whole other ball game and may create problems
