Long says the potential to study large groups of people to see if there is useful data that can be collected is interesting. “But it does not replace any of the other things we should be doing, and the other steps that the NBA should be doing in terms of protecting their players, protecting their staff,” Long said. They should still be doing pools of testing and regular testing — all of those other things. Just don’t let it give us a false sense of security. Don’t stop wearing your mask because your Oura ring says you’re OK. You know, don’t skip testing because everybody’s Oura ring says they’re fine.”
