Some context: Charles Henry "Chuck" Noll (January 5, 1932 - June 13, 2014) was a professional American football player, assistant coach and head coach. His sole head coaching position was for the Pittsburgh Steelers of the National Football League (NFL) from 1969 to 1991. When Noll retired after 23 years, only three other head coaches in NFL history had longer tenures with one team. After a six-year playing career that included two NFL Championships as a member of his hometown Cleveland Browns, and several years as an assistant coach with various teams, in 1969 Noll took the helm of the then moribund Steelers (which had played in only one post-season game in its previous 36 years, a 21-0 loss), and turned it into a perennial contender.
Noll was drafted by the Cleveland Browns with the 239th pick in the 1953 NFL draft. During his first year, the Browns lost to the Detroit Lions in the NFL championship. The next two years the Browns were NFL champions. Although drafted as a linebacker, Coach Paul Brown used the undersized Noll as one of his "messenger guards" to send play calls to the quarterback (beginning with Otto Graham). Brown recalled that Noll soon "could have called the plays himself without any help from the bench. That's how smart he was." According to Art Rooney, Jr. (director of scouting for the Steelers before and during most of Noll's tenure), however, Noll felt demeaned by Brown's use of him in that way and "disliked the term 'messenger boy' so much that as coach of the Steelers he entrusted all the play calling to his quarterbacks." Noll was paid only $5,000 per season with the Browns and so while there he acted as substitute teacher at Holy Name High School and sold insurance on the side. During that period Noll also attended Cleveland-Marshall College of Law at night. He told Dan Rooney that he decided against becoming a lawyer because "he didn't really like the constant confrontation and arguments that come with being a lawyer." Instead, when Noll lost the starting guard position to John Wooten, he chose to retire at age 27 expecting to begin his coaching career at his alma mater. He was surprised, however, when he was not offered an open position on the University of Dayton coaching staff. Fortunately, he was offered a position by Sid Gillman on the staff of the Los Angeles Chargers, during its inaugural season.

On April 2, 2005, Hogan was inducted into the WWE Hall of Fame class of 2005 by actor and friend Sylvester Stallone. At WrestleMania 21 on April 3, Hogan came out to rescue Eugene, who was being attacked by Muhammad Hassan and Khosrow Daivari. The build-up to Hogan's Hall of Fame induction and preparation for his WrestleMania angle was shown on the first season of Hogan Knows Best. The next night on Raw, Hassan and Daivari came out to confront and assault fan favorite Shawn Michaels. The following week on Raw, Michaels approached Raw General Manager Eric Bischoff demanding a handicap match with Hassan and Daivari. Bischoff refused, but told Michaels if he found a partner he would be granted a tag team match. Michaels then made a plea for Hogan to team with him. On the April 18 episode of Raw, Hassan again led an attack on Michaels until Hogan appeared, saving Michaels and accepting his offer. At Backlash, Hassan and Daivari lost to Hogan and Michaels. Hogan then appeared on July 4 episode of Raw, as the special guest of Carlito on his talk-show segment Carlito's Cabana. After being asked questions by Carlito concerning his daughter Brooke, Hogan attacked Carlito. Kurt Angle then also appeared, making comments about Brooke, which further upset Hogan, who was eventually double teamed by Carlito and Angle, but was saved by Shawn Michaels. Later that night, Michaels and Hogan defeated Carlito and Angle in a tag team match; during the post-match celebration, Michaels performed the Sweet Chin Music on Hogan and walked off. The following week on Raw, Michaels appeared on Piper's Pit and challenged Hogan to face him one-on-one for the first time. Hogan appeared on Raw one week later and accepted the challenge. The match took place at SummerSlam, which Hogan won. After the match, Michaels extended his hand to him, telling him that he "had to find out for himself", and Hogan and Michaels shook hands as Michaels left the ring to allow Hogan to celebrate with the crowd. Prior to WrestleMania 22 in April 2006, Hogan inducted friend and former announcer "Mean" Gene Okerlund into the WWE Hall of Fame class of 2006.
