He was the 2011 NFL Rookie of the Year, is a three-time Pro Bowler, and was named to the NFL All-Pro First Team in 2015.
Document 2: 2012 Jacksonville Jaguars season: The Jacksonville Jaguars season was the franchise's 18th season in the National Football League. It was the first under the new ownership of Shahid Khan and the first season for head coach Mike Mularkey. The Jaguars entered the season hoping to improve on their 5–11 record from 2011 and return to the playoffs for the first time since 2007, but did not and were eliminated from postseason contention. This season marked the third time in the last five seasons in which the Jaguars finished fourth in the AFC South. The Jaguars finished with a 2–14 record, not only tying the Kansas City Chiefs for the leagues worst record of 2012, but it was also the worst in franchise history. Their 1–7 record at home was also their lowest home record in team history.
Document 3: 2011 San Francisco 49ers season: The 2011 San Francisco 49ers season was the franchise's 66th season overall, and 62nd in the National Football League (NFL). It is the first season under head coach Jim Harbaugh and general manager Trent Baalke. The 49ers rebounded from their disappointing 2010 season to end their streak of eight consecutive non-winning seasons. After defeating the St. Louis Rams in week 13 and attaining a 10–2 record, the team clinched the NFC West and made their first playoff appearance since 2002 (under head coach Steve Mariucci). The 49ers ended the regular season with a 13–3 record, their best since 1997 and earned a bye in the first round of the playoffs. In the Divisional Playoffs they defeated the New Orleans Saints 36–32 and were in the NFC Championship for the first time since 1997 where they lost against the New York Giants 20–17 in overtime, coming just short of returning to the Super Bowl for the first time since 1994. Despite their most successful season in years, the 49ers were 31st in the league in third down conversion percentage in the regular season (29.1) and were 17.9 percent in the playoffs.
Document 4: 2012 St. Louis Rams season: The St. Louis Rams season was the team's 75th season in the National Football League, the 18th overall in St. Louis and the first under new head coach Jeff Fisher. Finishing at 7–8–1, they improved on their 2–14 record from 2011. In Week 10 against the San Francisco 49ers, the game ended in a 24–24 tie, the first since the 2008 NFL season. It was Sam Bradford's second and final full season as the Rams starting quarterback as two torn ACLs sidelined him for much of the next season and the entire 2014 season.
Document 5: 2003 St. Louis Rams season: The 2003 St. Louis Rams season was the team's 66th year with the National Football League and the ninth season in St. Louis. The Rams were coming off a disappointing 7–9 season and former MVP Kurt Warner was demoted to backup quarterback; Marc Bulger earned the starting job after replacing Warner in 2002 and winning six of his seven starts. Though many agree that The Greatest Show on Turf ended after the 2001 season, the Rams nonetheless finished 12–4, winning the NFC West, only to lose to the eventual NFC champions Carolina Panthers.
Document 6: 2007 St. Louis Rams season: The 2007 St. Louis Rams season was the 70th season for the team in the National Football League and their 13th in St. Louis, Missouri. This was the third worst season for the Rams during their time in St. Louis. The team looked to improve on its 8-8 record from 2006. However, the Rams slumped early, losing their first 8 games of the season heading into their bye week. Following their bye, they would beat both New Orleans and San Francisco on the road before losing 5 of their last 6 games to conclude the season. The Rams 0-8 start to the season is the worst in franchise history and matched their 3rd ever longest losing streak. The Rams also went 1-7 at home in 2007, the worst in franchise history until it was broken by the 2009 team 2 years later. The Rams defense was dismal, and was the biggest scar on the team the entire season, as they allowed the 2nd most points in the league during the season with 438.

Document 9: 2014 St. Louis Rams season: The St. Louis Rams season was the franchise's 77th season in the National Football League, the 20th overall in St. Louis and the third under head coach Jeff Fisher. The Rams attempted to reach a playoff berth for the first time since their 2004 season, but were officially eliminated in their loss against Arizona in Week 15. The Rams failed to improve on their 7–9 record from 2013, finishing 6–10 in 2014. The Rams' 2014 season was notable for their numerous starting quarterbacks including Austin Davis, Shaun Hill, and Sam Bradford, the last of whom was injured before the season began. Despite the lack of stability at the position, the Rams defeated both defending conference champions, Super Bowl participants, and 2014 division winners, the Seattle Seahawks and Denver Broncos, plus also shutting out two teams in consecutive weeks: the Oakland Raiders and Washington Redskins.
Document 10: 2010 St. Louis Rams season: The 2010 St. Louis Rams season was their 73rd season for the franchise, and their 16th overall in St. Louis. St. Louis greatly improved on their near winless record of 1–15 from the 2009 season by achieving more total victories, with a record of 7–9, than in their previous 3 years. Since the start of the 2007 NFL season, the Rams had won just 6 combined games, and have not qualified for the playoffs since 2004. In the 2010 NFL Draft, the Rams had the number 1 overall pick, which they picked Sam Bradford from Oklahoma. This year marked their second season under head coach Steve Spagnuolo. The Rams played all of their home games at the Edward Jones Dome, in St. Louis, Missouri.
Document 11: Sam Bradford: Samuel Jacob Bradford (born November 8, 1987) is an American football quarterback for the Minnesota Vikings of the National Football League (NFL). Bradford attended Putnam City North High School in Oklahoma City, where he starred in football, basketball and golf. As a senior quarterback in 2005, he threw for 2,029 yards and 17 touchdowns in 12 games. Bradford was not highly recruited coming out of high school, but he did receive a scholarship offer from the University of Oklahoma, which he accepted. After a redshirt season in 2006, Bradford threw for 3,121 yards and 36 touchdowns as a redshirt freshman. That set the stage for a phenomenal 2008 year, when Bradford became only the second sophomore to win the Heisman Trophy as he was the trigger man for the highest-scoring offense in NCAA history, throwing for 4,464 yards with 48 touchdowns and just six interceptions. He again led the nation in passing and also added five rushing touchdowns as the Sooners went 12-1 and advanced to the BCS national title game. Bradford declared for the NFL draft following the 2009 season and was drafted by the St. Louis Rams with the first overall pick in the 2010 NFL Draft.

Document 13: 2011 Minnesota Vikings season: The 2011 Minnesota Vikings season was the franchise's 51st season in the National Football League, and the first full season under head coach Leslie Frazier, who served as the team's interim head coach for the final six games of the 2010 season. It was also supposed to mark the first season with new starting quarterback Donovan McNabb, who had enjoyed great success with the Eagles but had a subpar year with the Redskins in 2010. McNabb played respectably, having a passer rating of 82.9 and only turning the ball over twice, but his 1–5 record as starter led to him being benched in favor of rookie Christian Ponder in Week 6, and McNabb was later waived on December 1, 2011. The team failed to improve on their 6–10 record from 2010, going 2–6 before their bye week, before being eliminated from playoff contention in week 12 with a 2–9 record. The team also suffered its first six-game losing streak since the 1984 season. Despite a poor year for the team, Jared Allen set a franchise record for most sacks in a season with 22. The team led the league in sacks with 50, but also tied a team record for fewest interceptions caught in a season with only 8.
Document 14: 2011 San Diego Chargers season: The San Diego Chargers season was the franchise's 42nd season in the National Football League and the 52nd overall. The team failed to improve on its 9–7 record from 2010, and finished in a three-way tie with the Denver Broncos and Oakland Raiders for the AFC West division title, with an 8–8 record, but lost the tiebreaker to the Broncos and missed the playoffs for a second consecutive season. For Norv Turner, this was his fifth season as the head coach of the Chargers. The Chargers had the 18th pick in the 2011 NFL Draft.

CBS Sports draft analyst Rob Rang called Luck the best prospect he had ever scouted, while the "Kansas City Star" put him in line with LeBron James and Bryce Harper as "the most hyped amateurs in recent sports memory."
