Nuguse was cooked. That's all that happened. He went out too fast for what he had that day and did well to hold on to that point, before stumbling on the rail because he was so tired. The Va Tech guy had closed from 3 seconds to within 1, and it was going to be close at best. I assume he'll be very, very fast at NCAA's, but even if he doesn't recover, he's already run a college record 7:38 3000m this year.
