The NFL scouting combine is a week-long showcase occurring every February at Lucas Oil Stadium in Indianapolis, where college football players perform physical and mental tests in front of National Football League coaches, general managers, and scouts. With increasing interest in the NFL draft, the scouting combine has grown in scope and significance, allowing personnel directors to evaluate upcoming prospects in a standardized setting. Its origins have evolved from the National, BLESTO, and Quadra Scouting organizations in 1977 to the media event it has become today. Athletes attend by invitation only. Implications of one's performance during the combine can affect perception, draft status, salary, and ultimately career. The draft has popularized the term "workout warrior", whereby an athlete's "draft stock" is increased based on superior measurable qualities such as size, speed, and strength, despite having an average or sub-par college career. The 2014 NFL scouting combine occurred from February 19–25, 2014.
