 Look, for spectators, it's really fun. I mean, all of the country's biggest athletes competing against each other on one day. It's what more can you ask for? And within the sport, some people say this is the most fair way to do things because it doesn't leave room for subjectivity. But others say the system is unfair because it is just so final and it leaves no room for error, especially when a race plays out like it did last week when Team USA's A Thing Mo went down shortly into the 800-meter final.
