2009 NFL Draft: The 2009 NFL Draft was the seventy-fourth annual meeting of National Football League (NFL) franchises to select newly eligible football players.  The draft took place at Radio City Music Hall in New York City, New York, on April 25 and 26, 2009.  The draft consisted of two rounds on the first day starting at 4:00 pm EDT, and five rounds on the second day starting at 10:00 am EDT.  To compensate for the time change from the previous year and in an effort to help shorten the draft, teams were no longer on the clock for 15 minutes in the first round and 10 minutes in the second round.  Each team now had 10 minutes to make their selection in the first round and seven minutes in the second round.  Rounds three through seven were shortened to five minutes per team.  This was the first year that the NFL used this format and it was changed again the following year for the 2010 NFL Draft.  The 2009 NFL Draft was televised by both NFL Network and ESPN and was the first to have cheerleaders.  The Detroit Lions, who became the first team in NFL history to finish a season at 0–16, used the first selection in the draft to select University of Georgia quarterback Matthew Stafford.

Immaculate Reception: The Immaculate Reception is one of the most famous plays in the history of American football.  It occurred in the AFC of the National Football League (NFL), between the Pittsburgh Steelers and the Oakland Raiders at Three Rivers Stadium in Pittsburgh, Pennsylvania, on December 23, 1972.  With the Steelers trailing in the last 30 seconds of the game, Pittsburgh quarterback Terry Bradshaw threw a pass attempt to John Fuqua.  The ball bounced off the hands of Raiders safety Jack Tatum and/or Fuqua and, as it fell toward the ground, Steelers fullback Franco Harris scooped it up and ran for a game-winning touchdown.  The play has been a source of unresolved controversy and speculation ever since, as many people have contended that the ball touched only Fuqua or the ground before Harris caught it, either of which would have resulted in an incomplete pass by the rules at the time.  Kevin Cook's "The Last Headbangers" cites the play as the beginning of a bitter rivalry between Pittsburgh and Oakland that fueled a historically brutal Raiders team during the NFL's most controversially physical era.
