I'm looking at the CDC tables now. You are correct that oldrover's table is the wrong one. However, your guess at the real number is also wrong. The CDC table can be found here:
Coronavirus Disease 2019 (COVID-19) in the U.S. It shows that the death rate for Pats players is .5 for those under 30 and 1.3% for those over 30. No matter how you slice it, if a lot of NFL players get this, there is a good chance that some will die. And some will probably never play again due to organ damage (heart/lungs).
