I hope neither Mahomes or Gilmore gets sick. I am not an alarmist about COVID19 in young healthy players, but the pressure is now on Gooddell from a PR standpoint (at least).
But CDC recommendations are that if you are exposed to a known contact with COVID, you are supposed to self isolate for 14 days.
Maybe the NFL is different.
But, perception is everything. If there is a big out break on Chiefs with more players coming down with COVID, it will look bad that the NFL did not take steps to minimize the spread.
I agree, its unlikely that Mahomes would get sick, but the idea is to contain the spread and the pandemic. Therefore if Gooddelll does nothing with Mahomes (as I suspect( because he is the face of the league and then over the next 7 days multiple additional chiefs players, coaches and staff test positive then the blame can be appropriately placed on Gooddell.
