What pro sports draft consists of seven rounds in which it's 2011 draft was held in Radio City Music Hall?
National Football League Draft The National Football League Draft, also called the player selection meeting, is an annual event in which the National Football League (NFL) teams select eligible college football players. It serves as the league's most common source of player recruitment. 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. From this position, the team can either select a player or trade their position to another team for other draft positions, a player or players, or any combination thereof. The round is complete when each team has either selected a player or traded its draft position. Certain aspects of the draft, including team positioning and the number of rounds in the draft, have seen revisions since its first creation in 1936, but the fundamental methodology has remained the same. Currently the draft consists of seven rounds. The original rationale in creating the draft was to increase the competitive parity between the teams as the worst team would, ideally, have chosen the best player available.
NBA draft The NBA draft is an annual event dating back to 1947 in which the (now thirty) teams from the National Basketball Association (NBA) can draft players who are eligible and wish to join the league. These are typically college basketball players, but international players are also eligible to be drafted. College players who have finished their four-year college eligibility are automatically eligible for selection, while the underclassmen have to declare their eligibility and give up their remaining college eligibility. International players who are at least 23 years old are automatically eligible for selection, while the players younger than 22 have to declare their eligibility. Players who are not automatically eligible but have declared their eligibility are often called "early-entrants" or "early-entry candidates". The draft usually takes place at the end of June, during the NBA offseason. Since 1989, the draft has consisted of two rounds; this is much shorter than the entry drafts of the other major professional sports leagues in the United States and Canada, all of which run at least seven rounds. Sixty players are selected in each draft. No player may sign with the NBA until he has been eligible for at least one draft.
