Who: Maurice Greene, Shawn Crawford, Justin Gatlin and Coby Miller
Olympics: Athens 2004

After Justin Gatlin won gold in the 100 meter sprint and teammates Maurice Greene and Shawn Crawford took third and fourth, respectively, a gold in the 4x100 relay seemed like a foregone conclusion. However, poor execution of the baton handoffs doomed the squad and led to a disappointing silver medal behind Great Britain. Greene later revealed that the foursome had only practiced handoffs twice leading up to the Olympics.
