The NFL has a very sophisticated process for IDing COVID+ players. There's a reason why they find few true positives & it has nothing to do w precautions taken by players flying around the USA. Simply put, they know about the testing scam.

Interview w/ NFL Chief Medical Officer:

The theme is consistent: if you have the resources, you quickly find out that most COVID positives are not in fact positive. They expose the casedemic for what it is.

More: "An initial positive test will continue to be followed by two more tests ... But they now can be cleared on the same day if both test results immediately come back negative." https://www.espn.com/nfl/story/_/id/29782185/covid-19-testing-protocols-adjusted-minimize-false-positives
