Mark Messner

His biological father, Max Messner, was a linebacker for the Detroit Lions and Pittsburgh Steelers from 1960 to 1965.

Messner's parents divorced when he was young, and he was raised by his mother and stepfather, Del Pretty, who ran a piano store in Livonia, Michigan.

Messner referred to his biological father as the "fun" dad and Pretty as the "disciplinarian."

Mark W. Messner (born December 29, 1965) is a former American football player who played in the National Football League (NFL) as a linebacker for the Los Angeles Rams during the 1989 NFL season.

Messner was born in Riverview, Michigan, a southern suburb of Detroit, in 1965.

He later noted that Pretty "raised me, fed me, spanked me, hugged me, took me to school, wrote me poems, came to all my football games and made me feel like the most important person in the world. Pretty was diagnosed with lymph node cancer in 1980 and eventually died from the disease in December 1989 when Messner was a rookie with the Los Angeles Rams.

Messner was a hyperactive child for whom football was an outlet to unleash his energy.

He grew up in Hartland, Michigan, and attended Hartland High School from 1980 to 1981 before transferring to Detroit Catholic Central High School, which was then located in Redford, Michigan.

He played at the tight end and nose guard positions for Catholic Central in 1982 and 1983 and earned all-state and high school All-American honors as a senior, and graduated in 1984.

He was later inducted into both the Catholic Central and Catholic League Halls of Fame.

Messner enrolled at the University of Michigan in 1984 and played college football as a defensive tackle for head coach Bo Schembechler's Michigan Wolverines football teams from 1985 to 1988.

At six feet, three inches, Messner was small for his position.

He adjusted for his size by playing with speed and intelligence.

Messner once described his approach as follows: "I try to move with quickness toward his weakness. I try to get away from where he is leaning, like a matador steps around a bull."

Messner was a redshirt who did not play during the 1984 season.

He started every game, 49 in all, at defensive tackle for Michigan from 1985 to 1988.

He was the first position player ever to be selected as a first-team All-Big Ten Conference player all four years.

Despite his lack of college experience, Messner set a new Michigan record in 1985 with 11 quarterback sacks and also totaled 71 tackles and 14 tackles for loss.

He was also selected as a first-team defensive lineman on the 1985 All-Big Ten team.

He was also named the Defensive Player of the Game in the 1986 Fiesta Bowl after he registered nine tackles, forced a fumble, and recovered another.

In his second year, Messner started all 13 games at defensive tackle for the 1986 Michigan team that compiled an 11-2 record, tied for the Big Ten Conference championship, and lost to Arizona State in the 1987 Rose Bowl.

For the second consecutive year, Messner was selected as a first-team defensive lineman on the All-Big Ten team.

He was selected as a first-team All-American by the Sporting News in 1987 and was a consensus All-American in 1988.

He set still holds Michigan records for quarterback sacks in a game (5), career tackles for loss (70), and career sacks (36).

As a junior, Messner again started every game, 12 in all, at defensive tackle for the 1987 Wolverines.

He had 11 sacks during the 1987 season.

His five sacks against Northwestern on October 31, 1987, remains a Michigan single-game record.

At the end of the season, he was selected by the Sporting News as a first-team defensive lineman on the 1987 All-America Team.

He was also voted by his teammates as Michigan's defensive player of the year.

In a 1988 interview with Mitch Albom, Messner referred to Pretty as "the most important person in my life. He's the reason I do what I do, and try as hard as I try."

Prior to the 1988 season, the Sporting News featured a photograph of Messner and coach Schembechler on the cover of its preseason issue ranking Michigan #1 in the country.

During the 1988 season, Messner started every game at defensive tackle for the fourth consecutive year.

In all, he started 49 consecutive games for Michigan starting with the opening game of his redshirt freshman year.

He sustained a serious knee injury in the 1989-90 NFC Championship Game against the San Francisco 49ers and never played in another game.

Messner played college football for the University of Michigan.

The Los Angeles Times in January 1989 called him "a quarterback's worst enemy."

Another writer described him as "a combination Dennis the Menace and Henry David Thoreau, a philosopher with a cowlick" and "Aristotle in a jockstrap."

Messner noted that it was his goal to play with "youthful intensity" like "a young kid."

As a redshirt freshman, he started all 12 games at defensive tackle for the 1985 Michigan Wolverines football team that compiled a 10-1-1 record, was ranked #2 in the final AP Poll, held opponents to 75 points in the regular season (6.8 points per game), and defeated Nebraska in the 1986 Fiesta Bowl.

He was inducted into the University of Michigan Athletic Hall of Honor in 2014.
