It's obviously not a great analogy, but MLB appears to be managing with one outage I know of. I think it is POSSIBLE the SEC MIGHT get through ten games without an outbreak that cripples any team. Possibility of course means anywhere from 1% to 99%.
More likely, I think, is one player tests positive and has to quarantine (not play) even if it's a false positive. That casts a shadow on the entire team obviously. What then? The other players on Friday might test negative but actually be positive by Saturday (contagious). Dunno.
Too many possible outages I think to view them as anything but probable.
