Question: What pro sports draft consists of seven rounds in which it's 2011 draft was held in Radio City Music Hall?

<P0-S0> K9 Professional/Protection Sports, also known as K9 Pro Sports was founded in 1992. <P0-S1>  The first Personal Protection and Patrol dog certification trial was held in Ciudad Juarez, Mexico. <P0-S2>  Events of the very first trial were highlighted in Dog Sports Magazine. <P0-S3>  The popularity of these certification trials soon crossed over the border into Texas. <P0-S4>  This type of trial was often referred to as a K9 Rodeo. <P0-S5>  As the organization continued to grow, so did the publicity of its events. <P0-S6>  K9 Pro Sports was featured in the "Having it all" article of the December, 1999 issue of Dog and Kennel magazine, a national publication for dog owners and dog enthusiasts. <P0-S7>  The first K9 Pro Sports National Championship was held in 2000, in Fort Worth, Texas. <P0-S8>  The first International Championship trial was held the following year, securing K9 Pro Sports position as a recognized international organization. <P0-S9>  There are now sanctioned trials on three continents, North America, Europe, and Australia. <SEP> <P1-S0> 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. <P1-S1>  It serves as the league's most common source of player recruitment. <P1-S2>  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. <P1-S3>  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. <P1-S4>  The round is complete when each team has either selected a player or traded its draft position. <P1-S5>  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. <P1-S6>  Currently the draft consists of seven rounds. <P1-S7>  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. <SEP> <P2-S0> The 2011 NFL Draft was the 76th installment of the annual NFL Draft, where the franchises of the National Football League select newly eligible football players. <P2-S1>  Like the 2010 draft, the 2011 draft was held at Radio City Music Hall in New York City, New York, over three days: this year, the first round took place on Thursday, April 28, 2011; the second and third rounds took place on Friday, April 29; with the final four rounds on Saturday, April 30, 2011. <SEP> <P3-S0> Idina Menzel: Live at Radio City was a concert by American singer-songwriter and actress Idina Menzel at Radio City Music Hall in New York City, New York on June 16, 2014. <P3-S1>  In the wake of the success of Disney's popular animated film "Frozen "(2013), in which Menzel starred as Elsa, Menzel announced in April 2014 that she will be headlining a one-night-only concert at Radio City Music Hall on her break from her eight shows a week.
