While Sha'Carri is suspended, she is not allowed to practice with her Olympic teammates. The US team does a lot of hand-off practice between now and when Sha'Carri would be eligible to return. I'm guessing USATF does not want to risk a dropped baton on an exchange between Sha'Carri and another athlete, due to lack of practice. I believe USATF would have selected her for the relay pool if she were allowed to practice with her teammates. What do you think about this theory?
