The NFL Scouting Combine will be held February 20-26 in Indianapolis at Lucas Oil Stadium. Last year, 327 players were initially invited and 216 were drafted, per SB Nation. Per National Football Scouting, which oversees the Combine, the players selected to participate are determined by a selection committee made up of directors from the National and BLESTO scouting services along with members of various NFL player personnel departments.

Over the course of the week, NFL teams have the ability to watch players undergo a series of on-field exercises ranging from the 40-yard dash and the bench press to position-specific drills. Players are also examined by NFL medical staffs to review injury history. Teams can also have sitdown interviews with up to 60 prospects to learn more about the players. The NFL Combine is also where the Wonderlic Test is administered. The Wonderlic Test is an exam of 50 questions designed to test a player's intelligence.
