CDC guideline is for 10 days of isolation following a positive test if asymptomatic.

There is no guidance for taking another COVID-19 test to shorten the isolation period.
Also, while a positive antigen test for screening purposes in an asymptomatic individual has a reasonable chance of being a false positive, that is not the case if you are doing the test in a close contact of a positive case or in someone who is symptomatic.  In that case, a positive test is much more likely to be a true positive, so confirmation with a PCR test is unnecessary.

I think the parents of the kids involved believe that a negative PCR test after a positive antigen test should be governing in vaccinated individuals who are asymptomatic, independent of the close contact with a positive case. They view it not as a second text but rather part of the first one. I can see their reasoning, but OTOH if you have been in close contact with somebody who has for certain COVID isolating seems like a prudent course of action. This situation is not typical of the athletes who are/were impacted.

The real problem IMHO is it wasn't made clear to the athletes that they were subject to testing requirements from day 1. The fact they weren't being routinely tested (apparently) doesn't exempt them from the requirement.
