IN: 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.

From 1974 to 1976, Dierdorf started every game at right tackle for the Cardinals during a three-year span in which the team compiled records of 10-4, 11-3, and 10-4 under head coach Don Coryell. In 1977, Dierdorf sustained a broken jaw and missed two games to injury as the Cardinals fell to 7-7. In 1978, Dierdorf started all 16 games at right tackle for the Cardinals. During his peak years from 1974 to 1978, Dierdorf was regarded as one of the best offensive lineman in the NFL. He was selected by the National Football League Players Association as the Offensive Lineman of the Year for three consecutive years from 1976 to 1978. The Cardinals' offensive line, led by Dierdorf, Conrad Dobler, and Tom Banks, led the NFL with the fewest sacks allowed for three years (and the National Football Conference for five years) in the mid-1970s. In 1975, the group set an NFL record, allowing only eight sacks in 14 games. Dierdorf did not allow a sack during the entire 1976 and 1977 seasons. His streak ended in the first game of the 1978 season when Chicago Bears defensive end Tommy Hart tallied two sacks against Dierdorf. Dierdorf had not given up a sack since the 1975 NFC Divisional playoff game when Jack Youngblood sacked Jim Hart. Dierdorf was selected to play in the Pro Bowl for five consecutive years from 1974 to 1978. Dierdorf also received first-team All-NFL honors as follows: in 1975 from the Pro Football Writers Association (PFWA); in 1976 from the Associated Press (AP), PFWA, Newspaper Enterprise Association (NEA), and Pro Football Weekly (PFW); in 1977 from AP, PFWA, NEA, and PFW; and in 1978 from AP, PFWA, NEA, PFW. He was named as the NFC choice for the NFLPA/Coca-Cola Offensive Lineman of the Year Award three straight years (1976-78) and was the Seagram's Seven Crowns of Sports Offensive Lineman of the Year in 1975. He also won the Forrest Gregg Award for NFL Offensive Lineman of the Year in 1975.

IN: 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.

Born and raised in Marshall, Texas, to Alma and Yelberton Abraham Tittle Sr., Yelberton Abraham Tittle Jr. aspired to be a quarterback from a young age. He spent hours in his backyard throwing a football through a tire swing, emulating his neighbor and boyhood idol, Sammy Baugh. Tittle played high school football at Marshall High School. In his senior year the team posted an undefeated record and reached the state finals. After a recruiting battle between Louisiana State University and the University of Texas, Tittle chose to attend LSU in Baton Rouge, Louisiana, and play for the LSU Tigers. He was part of a successful 1944 recruiting class under head coach Bernie Moore that included halfbacks Jim Cason, Dan Sandifer, and Ray Coates. Freshmen were eligible to play on the varsity during World War II, so Tittle saw playing time immediately. He later said the finest moment of his four years at LSU was beating Tulane as a freshman, a game in which he set a school record with 238 passing yards. It was one of two games the Tigers won that season. Moore started Tittle at tailback in the single-wing formation his first year, but moved him to quarterback in the T formation during his sophomore season. As a junior in 1946, Tittle's three touchdown passes in a 41-27 rout of rival Tulane helped ensure LSU a spot in the Cotton Bowl Classic. Known notoriously as the "Ice Bowl", the 1947 Cotton Bowl pitted LSU against the Arkansas Razorbacks in sub-freezing temperatures on an ice-covered field in Dallas, Texas. LSU moved the ball much better than the Razorbacks, but neither team was able to score, and the game ended in a 0-0 tie. Tittle and Arkansas end Alton Baldwin shared the game's MVP award. Following the season, United Press International (UPI) placed Tittle on its All-Southeastern Conference (SEC) first-team. UPI again named Tittle its first-team All-SEC quarterback in 1947. In Tittle's day of iron man football, he played on both offense and defense. While on defense during a 20-18 loss to SEC champion Ole Miss in his senior season, Tittle's belt buckle was torn off as he intercepted a pass from Charlie Conerly and broke a tackle. He ran down the sideline with one arm cradling the ball and the other holding up his pants. At the Ole Miss 20-yard line, as he attempted to stiff-arm a defender, Tittle's pants fell and he tripped and fell onto his face. The fall kept him from scoring the game-winning touchdown. In total, during his college career Tittle set school passing records with 162 completions out of 330 attempts for 2,525 yards and 23 touchdowns. He scored seven touchdowns himself as a runner. His passing totals remained unbroken until Bert Jones surpassed them in the 1970s.
