It's hard to see any sense in which the mass field rush after the Clemson game did not meet the criteria of a super-spreader type event. Incubation times can be as low as 4 days, and Notre Dame is doing significant random testing, exceeding 500 tests per day. So far, 5 days later, no signature from the field rush has emerged. In fact, cases are trending down as of yesterday. But, the next 2-4 days should be very telling.
