Who: US men's basketball
Olympics: Seoul 1988

The last US Olympic team consisting entirely of amateurs turned out to be quite the disappointment. Despite having future NBA stars David Robinson, Dan Majerle, and Mitch Richmond along with collegiate superstar Danny Manning, the roster was also filled out with no-names like Jeff Grayer and Charles Smith. The loss to the Soviet Union in the semifinals is one of the biggest blemishes on coach John Thompson's resume. On the bright side, if the team had somehow pulled out the gold medal, we might not have ever seen the Dream Team.
