Marshall was drafted by the Giants in the second round out of Louisiana State University ( LSU ) in the 1983 NFL Draft . He was selected to the Pro Bowl for his performances in the 1985 , 1986 , and 1991 seasons and finished his career with 83 . 5 quarterback sacks in the regular season and another twelve sacks in the post season . He averaged nearly ten sacks a season from 1985 to 1991 , and posted double digit sack totals 3 times . He currently is a professor of Sports Management and Executive - in - Residence at Seton Hall University and runs an annual instructional camp for youth football players in south Florida . Early life and college . Marshall was born in Franklin , Louisiana . He was the oldest of seven children , whose father , Leonard Marshall Sr . , was a foreman at a shipyard . Initially , Marshall ' s father did not like the idea of his son playing football , as he thought it was " a stupid game " that would prevent him son from doing more productive things . Later in his life however , Marshall Sr . expressed happiness over his son ' s success , and even rooted against his beloved Dallas Cowboys when his son ' s Giants teams played them . At the age of 18 , Leonard met his future wife Janice Milburn , who was eight years his senior . She had a son , Rod Milburn Jr . , who is the son of Olympic Gold Medal winning high hurdler Rod Milburn . Milburn Jr . was eight years old when Marshall and Milburn began dating . Marshall majored in Business Management at LSU . He chose the school over the University of Alabama and its Hall of Fame coach Bear Bryant , because of the school ' s academic reputation and because it allowed him to stay close to home . Marshall played a crucial role in LSU ' s 1982 victory over Alabama , making several key tackles and prompting Bryant to state his regret in a post - game press conference for his inability to recruit Marshall . The team finished 8 – 3 – 1 and narrowly lost , 21 – 20 , to the University of Nebraska in the Orange Bowl . He was named the team ' s defensive Most Valuable Player for his performance in the 1982 season . Professional career . Marshall was selected with the 37th overall selection ( the fourth defensive lineman taken ) in the 1983 NFL Draft . At the time Los Angeles Raiders managing general partner Al Davis described him as the steal of the draft . In his rookie season Marshall initially struggled with weight problems which drew the ire of the coaching staff . After trimming down , Marshall made an impact and played strongly against the run but was unable to mount much of a pass rush and finished with a meager . 5 sacks on the season . He improved rapidly and recorded 6 . 5 sacks in 1984 . He recorded several key tackles to help the Giants preserve a crucial 16 – 13 win over the Los Angeles Rams during the Wild - Card round of the playoffs . His emergence as a pass rusher continued in 1985 and he finished with 15 . 5 sacks , and was named NFL defensive lineman of the year . He repeated that honor in 1986 as he finished with 12 sacks . He teamed with Hall of Fame linebacker Lawrence Taylor to form a potent pass rush on the right side of the Giants defense . The Giants finished 14 – 2 and advanced to the Super Bowl where they faced the Denver Broncos . Marshall recorded two sacks in the Giants 39 – 20 victory . Marshall recorded eight sacks in ten games played in the strike shortened 1987 season . The Giants struggled to a 6 – 9 – 1 record in 1987 before rebounding to finish 10 – 6 in 1988 . Marshall again recorded eight sacks as he split time with fellow defensive end John Washington . Marshall recorded 9 . 5 sacks in 1989 , and the Giants lost in the first round of the playoffs to the Rams .

He reported late , and after initially struggling to regain his job , recovered to record 4 . 5 sacks during the season . The Giants started out 10 – 0 and finished 13 – 3 . They advanced to the NFC Championship game where the two - time defending Super Bowl champions San Francisco 49ers awaited them . Marshall is probably best known for his hit that knocked Hall of Fame quarterback Joe Montana out of that game . In the fourth quarter he hit Montana so hard that he suffered a bruised sternum , bruised stomach , cracked ribs , and a broken hand . This would be the last game Montana would ever start for the 49ers . In 2007 , the hit was ranked as the third most " devastating hit " in NFL history by Fox Sports Net , and the third most " devastating hit " in sports history by " The Best Damn Sports Show Period " . Marshall finished the game with four tackles , two sacks , and two forced fumbles , and was named NFL defensive player of the week . He also recorded one sack in the Giants Super Bowl XXV victory over the Buffalo Bills . Marshall continued to play at a high level in 1991 , recording 11 sacks . He clashed with new Giants coach Ray Handley however , and got into a well publicized shouting match with him during halftime of a game against Dallas early in the 1992 season . He recorded four sacks in 1992 and left the Giants via free agency following the season . After a season each with the New York Jets and Washington Redskins , in which he recorded two sacks in both years , Marshall retired at the age of 33 . In 1996 he signed a ceremonial contract which allowed him to retire as a Giant . Upon signing the contract he stated , " I wanted to retire as a Giant because it ' s where my career began . They were people who believed in my talents and helped mold me into the man I am today , and I wanted to thank them for that .
