Problem: Daniel Lee Dierdorf (born June 29, 1949) is a former American football offensive lineman and current sportscaster. A native of Canton, Ohio, Dierdorf played college football for the University of Michigan from 1968 to 1970 and was selected as a consensus first-team All-American in 1970 and a first-team All-Big Ten Conference player in 1969 and 1970. He was inducted into the University of Michigan Athletic Hall of Honor in 1996 and the College Football Hall of Fame in 2000. Dierdorf played professional football in National Football League (NFL) with the St. Louis Cardinals for 13 seasons from 1971 to 1983.

On September 9, 1979, Dierforf sustained torn ligaments in his left knee during an extra point attempt in the second quarter of the second game of the season against the New York Giants. After the game, Dierdorf said, "The knee was completely out of the socket. It moved a couple of inches off to the side. My leg was all twisted around and my foot was pointing in the wrong direction. It was painful. Very painful." Dierdorf was carried off the field on a stretcher, underwent knee surgery, and missed the remainder of the 1979 season.  Dierdorf returned to the Cardinals in 1980, starting all 16 games for the team at right tackle in both the 1980 and 1981 seasons. In 1980, he was selected to play in the Pro Bowl and was selected as a first-team All-NFL player by the NEA. In 1982, Dierdorf moved to center and was the starter at that position for all nine games in a strike-shortened season.  In 1983, Dierdorf returned to his right tackle position and appeared in seven games, only four as a starter. On October 11, 1983, after the Cardinals began the season with a 1-5 record, Dierdorf announced that he would retire at the end of the 1983 season. At the press conference announcing his retirement, Dierdorf said, "This was an easy decision for me to make. . . . Physically, I just can't play the type of game I want to." He added: "Ninety-five percent of me is sad that I'm retiring, but my knees are very, very happy."

Question:
Yelberton Abraham Tittle Jr. (October 24, 1926 - October 8, 2017), better known as Y. A. Tittle, was a professional American football quarterback. He played in the National Football League (NFL) for the San Francisco 49ers, New York Giants, and Baltimore Colts, after spending two seasons with the Colts in the All-America Football Conference (AAFC). Known for his competitiveness, leadership, and striking profile, Tittle was the centerpiece of several prolific offenses throughout his seventeen-year professional career from 1948 to 1964. Tittle played college football for Louisiana State University, where he was a two-time All-Southeastern Conference (SEC) quarterback for the LSU Tigers football team.
A photo of a dazed Tittle in the end zone taken by Morris Berman of the Pittsburgh Post-Gazette on September 20, 1964, is regarded among the most iconic images in the history of American sports and journalism. Tittle, in his 17th and final season, was photographed helmet-less, bloodied and kneeling immediately after having been knocked to the ground by John Baker of the Pittsburgh Steelers and throwing an interception that was returned for a touchdown at the old Pitt Stadium. He suffered a concussion and cracked sternum on the play, but went on to play the rest of the season.  Post-Gazette editors declined to publish the photo, looking for "action shots" instead, but Berman entered the image into contests where it took on a life of its own, winning a National Headliner Award. The photo was published in the October 2, 1964, issue of Life magazine. It is regarded as having changed the way that photographers look at sports, having shown the power of capturing a moment of reaction. It became one of three photos to hang in the lobby of the National Press Photographers Association headquarters, alongside Raising the Flag on Iwo Jima and the Hindenburg disaster. A copy now hangs in the Pro Football Hall of Fame.  After at first having failed to see the appeal of the image, Tittle eventually grew to embrace it, putting it on the back cover of his 2009 autobiography. "That was the end of the road," he told the Los Angeles Times in 2008. "It was the end of my dream. It was over." Pittsburgh player John Baker, who hit Tittle right before the picture was taken, ran for sheriff in his native Wake County, North Carolina in 1978, and used the photo as a campaign tool. He was elected and went on to serve for 24 years. Tittle also held a fundraiser to assist Baker in his bid for a fourth term in 1989.
