The National Football League Draft, also called the Player Selection Meeting, is an annual event which serves as the league's most common source of player recruitment. The NFL Draft takes place on the last Thursday, Friday, and Saturday in April. The first round is on Thursday, the second and third rounds are on Friday, and the fourth-seventh rounds are on Saturday. In order to be eligible for the NFL Draft, a player must either be redshirt sophomore, junior, or senior. Once you declare for the draft, a player is not allowed to go back and play college football. The basic design of the draft is that each team is given a position in the drafting order in reverse order relative to its record in the previous year, which means that the last place team is positioned first. 1-20 picks are determined based on teams that miss the playoffs. The number one pick belongs to the team that had the worst regular season record and the number 20 pick belongs to the team that had the best regular season record in which they missed the playoffs. 21-24 picks are given to teams which were eliminated in the first-round of the playoffs and 25-28 picks are given to teams which were eliminated in the second-round of the playoffs. The 29 and 30 picks are given to the teams which were eliminated in the third-round of the playoffs. The 31st pick is given to the team which lost the Super Bowl. and 32nd pick to the team who won the Super Bowl. Teams are allowed to make trades and acquire extra picks. Some teams receive compensatory picks. This is based on salary, playing time, and postseason honors of the free agents each team lost during the previous off season. No team usually receives a compensatory pick until at least the third round.
