The NFL Scouting Combine is a week-long showcase occurring every February at Lucas Oil Stadium (and formerly at the RCA Dome until 2008) 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 stem from the National, BLESTO, and Quadra Scouting organizations in 1977. Athletes attend by invitation only. An athlete's performance during the combine can affect their draft status and salary, and ultimately their 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. History Tex Schramm, the president and general manager of the Dallas Cowboys from 1960 to 1989, proposed to the NFL competition committee a centralization of the evaluation process for NFL teams. Prior to 1982, teams had to schedule individual visits with players to run them through drills and tests. The national invitational camp (NIC) was first held in Tampa, Florida, in 1982. It was originated by National Football Scouting, Inc. as a means for member organizations to look at NFL draft prospects. For non-member teams, two other camps were created and used 1982–1984. The NIC was held in New Orleans, Louisiana, in 1984. It was renamed the NFL Scouting Combine following the merger of the three camps in 1985 to cut the cost of running the extra camps. It was held in Arizona in 1985 and once again in New Orleans in 1986 before permanently moving to Indianapolis in 1987. Tests and evaluations Tests and evaluations include: 40-yard dash Bench pressing of Vertical jump Broad jump 20-yard shuttle 3 cone drill 60-yard shuttle Position-specific drills Interviews – each team is allowed 60 interviews in 15-minute intervals Physical and injury evaluations Drug screening Cybex test Wonderlic test Sports writers question whether these tests have any relationship with NFL performance. Empirical research published in 2011 found that the 40-yard dash, vertical jump, 20-yard shuttle, and 3 cone drill tests have limited validity in predicting future NFL performance, suggesting that a prospect's past performance in college is a better indicator of future NFL performance than the aforementioned physical ability tests. 20-yard shuttle
