I believe we are 100% guaranteed gold in the 400m relay

Right now, whether it's Japan or China, those who made it to the finals and those who didn't
are all slower than or similar to Joelvin Bwesa.
Naturally, including the other countries, China, and Japan, the other two runners in their 100m squads will be slower than their 100m specialists,
but even our 2nd or 3rd string runners are just as good as Joelvin Bwesa.
Unless there is a massive upset, I see this as a 100% gold medal guarantee for the relay.
