Born 1961. Leonard Marshall is an American american football player.
Leonard Allen Marshall Jr. (born October 22, 1961) is an American former professional football player who was a defensive lineman for twelve seasons in the National Football League (NFL). He spent the first ten seasons of his career with the New York Giants where he accumulated 79.5 sacks, ranking him third in team history. He was twice selected to the Pro Bowl and twice named NFL Defensive Lineman of the Year following the 1985 and 1986 seasons. He won two championships with the Giants, recording three and a half sacks in the two Super Bowl games which he played in.
Marshall is most famously known for his 1991 hit on Joe Montana that knocked him out of the NFC championship game, after which Montana would not play another regular season game for almost two years. After his time with the Giants, Marshall went on to play a season each for the New York Jets and Washington Redskins before retiring from football at the age of 33. Marshall played college football at Louisiana State University.
Marshall has been active in several business and entrepreneurial activities since retiring. He also has spent time as a football camp instructor, a football head coach, written a couple of books, an Executive in Residence at Seton Hall University, an adjunct professor at Seton Hall University, and a radio broadcaster who made several appearances on The Howard Stern Show for 6 years starting in 1985-1991.
In 2013, Marshall was diagnosed with chronic traumatic encephalopathy (CTE), a degenerative brain disease detected in a growing number of retired NFL players. He has been involved with efforts to spread awareness about the issue and concerns of his fellow teammates and colleagues. Marshall is currently on the board of Carver Bank of Harlem, PikeTx.com, The Concussion Legacy Foundation, CaringKind of New York, and several other non profits. He is also an Outside Advisor at Rockefeller Capital Management of New York City where he works alongside Edward Moldaver, James Lee and Steve Cohen.
Early life and college career 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 his 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. During his senior year, he recorded 53 tackles and 4 sacks Marshall also played a crucial role in LSU's 1982 victory over the University of Alabama, making several key tackles and prompting Hall of Fame coach Bear Bryant to state his regret after the game for not being able to successfully recruit Marshall. The team finished 8β3β1 that year and narrowly lost, 21β20, to Nebraska in the Orange Bowl.
Marshall graduated from Louisiana State University with a degree in Business Administration. He was later inducted into the LSU Hall of Fame in 2008.
Professional career Marshall was selected in the second round with the 37th overall pick by the New York Giants in the 1983 NFL draft. He was the fourth defensive lineman taken that year. At the time, Los Angeles Raiders managing general partner Al Davis described him as the steal of the draft. 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 only 0.5 sacks on the season. He improved significantly in 1984 however, recording 6.5 sacks. He also made several key tackles to help the Giants preserve a 16β13 win over the Los Angeles Rams during the wild-card round of the playoffs.
Marshall's emergence as a pass rusher continued in 1985 as he racked up 15.5 sacks, earning him a trip to the Pro Bowl and recognition as NFL defensive lineman of the year.
Marshall recorded 8 sacks in 10 games played during a strike-shortened 1987 season in which the Giants finished 6β9β1. He compiled another 8 sacks the following year as he split time with fellow defensive end John Washington. During the 1989 season Marshall collected 9.5 sacks, with the Giants losing in the first round of the playoffs that year to the Los Angeles Rams. Marshall later described the season as a lost opportunity as he felt the Giants had the best team in the league that year. He reported late, and after struggling initially to regain his starting job Montana was forced to leave the game and would not play another regular season game for almost two years (in December 1992), which ended up being his last game with the 49ers. and the third most "devastating hit" in sports history by The Best Damn Sports Show Period. It would also turn out to be the moment of Marshall's career that he came to be most well-known for. Marshall finished the game with four tackles, two sacks, and two forced fumbles, and was named NFL defensive player of the week. The Giants won the game 15β13 and advanced to Super Bowl XXV where they faced the Buffalo Bills. Marshall recorded the team's only sack in helping the Giants to a 20β19 victory, earning him his second Super Bowl ring. He ended up with four sacks on the year and entered into free agency afterwards. Marshall finished out his career playing a season each for the New York Jets and Washington Redskins.
Marshall retired from football at the age of 33. He later signed a ceremonial contract in 1996 that 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."
Marshall was selected to two Pro Bowls, and finished his career with 83.5 sacks in the regular season, and 7 in the postseason. His total of 79.5 as a Giant ranks him third in team history.

Life after football Teaching and mentoring Marshall hosted the Leonard Marshall Football Academy for a number of years, a football camp teaching the game's fundamentals to youth players between the ages 8 of 18.
Marshall served as a professor of Sports Management at Seton Hall's Stillman School of Business from 2004 to 2009.
Business activities Marshall was founder of Pro Star Athletic, one of the largest sports licensed apparel companies of the 1990s. He later negotiated the sale of the company to International Apparel Manufactures Group of New York in 1999.
Marshall was named Vice President of Philanthropic Development for Seeman Holtz Financial Group in 2007. In 2015, he was named Director of Strategic Initiatives and Brand Ambassador for the publicly traded restaurant chain The Original Soup Man.
Marshall owned and managed The Marshall and Fox Sports Asset Management Group and was CEO and owner of Capital Source Mortgage.
CTE diagnosis and advocacy In 2013 Marshall was diagnosed with chronic traumatic encephalopathy (CTE), a degenerative brain disease linked to repeated head trauma that has afflicted many former football players. Tests for the disease were performed at UCLA using newly developed technology that allowed detection in living patients for the first time. Marshall says he began to notice symptoms such as memory loss, severe headaches, and mood swings in 2006, and that his erratic behavior took a major toll on the personal relationships in his life, including his marriage.
Marshall was part of a class action lawsuit against the NFL that initially resulted in a $765 million settlement, but was later amended to allow for a payout expected to exceed $1 billion. Marshall is involved with efforts to educate the public about concussion and head trauma issues, serving as a speaker for both the Practice Like Pros and Brain Unity Trust organizations. He was featured in the documentary United States of Football examining the subject of concussions in the NFL and youth league football. Marshall also founded the Game Plan Foundation to provide assistance for former athletes suffering from neurological disorders.
In a December 2019 interview, Marshall wondered aloud whether he has been kept out of the Giants' Ring of Honor because of his outspoken advocacy. He said, βI donβt want to believe that, because I think that when you look back on the powers that be and the gentlemen that are running the team now ... I would believe these men have a lot of respect for what I did as a player, both on and off the field, within the community, and the surrounding area, and what I continue to do to support the New York football Giants. I think that yes, I have been a little outspoken about [CTE], because I feel like I have a platform which allows me to do that, and to help my brothers who canβt help themselves.β
Medical cannabis
Marshall uses cannabidiol (CBD), a chemical extract of the cannabis plant, to treat the symptoms of CTE that he suffers from. He credits CBD with significantly improving his quality of life since he first started medicating with it in February 2016.
Marshall has spoken publicly in support of cannabis as an effective treatment option for mitigating the symptoms of head trauma-related health issues. Marshall has stated that the NFL should make allowances for the use of cannabis products as a medical treatment for players.
Other Marshall hosted a radio show on WFAN in New York. Named The Leonard Marshall Show, it was recorded in Hollywood, Florida near his former residence in Boca Raton. Marshall currently provides pre-game and post-game commentary for Giants games on WFAN.
