The National Underclassmen Combine/NUC Sports is a professional, privately owned recruiting program and three-day training and assessment function for high school football players to display their skills and potential. It is one of the largest and most successful programs of its kind, the purpose of which is to connect talented football athletes with collegiate programs willing to offer them a scholarship. Notable players to go through the system include Joe Haden, cornerback for the NFL's Cleveland Browns, and Marcus Lattimore, star running back for the University of South Carolina. Founded by former University of Connecticut linebacker David Schuman, the first combine event was held in New Jersey in 2005.
