In 1984, Waters was signed as an undrafted free agent by Philadelphia Eagles head coach Marion Campbell. He returned a kickoff for an 89-yard game-winning touchdown against the Washington Redskins as a rookie in 1984. When Buddy Ryan took over for Campbell in 1986, he welcomed Waters' aggressive style as a fierce tackler and ferocious hitter, earning Waters a position in the starting lineup for the next eight years. He blossomed under defensive coordinatorBud Carson. His tackle of Los Angeles RamsquarterbackJim Everett in 1988 led to a rule prohibiting defensive players from hitting quarterbacks below the waist while they are still in the pocket; for a while, it was unofficially termed the "Andre Waters Rule". NFL broadcaster Dan Dierdorf notoriously nicknamed the Eagles defender "Dirty Waters". He scored a touchdown in 1989 when he took a lateral from William Frizzell after Reggie White caused a fumble by New York Giants quarterback Phil Simms. Waters served as part of the Eagles' defensive unit that was regarded as one of the league's all-time best, in 1991 ranking first statistically in both run and pass defense, as well as total defense. His hard-hitting style translated into leading the team in tackles for four seasons and endeared him with Philadelphia fans but often led to penalties and fines for some of his tackles. He led the Eagles in tackles in 1986, 1987, 1988 and 1991. He recorded 15 interceptions in 156 games. In 1994, he was replaced by Mike Zordich due to his contract ending.
Coaching career
After retiring as a player, Waters worked as a college football coach. In 1996, he joined the staff of Stump Mitchell at Morgan State as defensive backs coach. The following year under head coach Jim Leavitt, Waters took the same position on the upstart South Florida football program. He remained in that position until 1999. In 2000, Waters left South Florida to join the St. Louis Rams of the NFL as a coaching intern for training camp. In 2006, the St. Petersburg Times reported that Leavitt made Waters choose between South Florida and the internship out of concern that Waters would miss too much preparation time with South Florida. After his Rams internship, Waters returned to Tampa to be defensive coordinator at Paul R. Wharton High School in 2000. In 2001, Waters moved back to the college level as defensive backs coach at Alabama State. He later coached at St. Augustine's from 2002 to 2005 as defensive coordinator upon the football program's return from a 35-year hiatus. In 2006, Waters was defensive coordinator at Fort Valley State. In 2002, Waters joined the Detroit Lions in his second stint as an NFL coaching intern. In 2006, Waters described his disappointment in not getting a full-time NFL coaching job to The Philadelphia Inquirer reporter Phil Sheridan. He remained very close to his former Eagles coach Buddy Ryan, whom Waters said he tried to emulate in his own coaching career.
Death
Waters committed suicide shortly after 1 a.m. on November 20, 2006, according to the Hillsborough County Sheriff's Office, dying of a gunshot to the head. He was at his home in Tampa, Florida where he was discovered by his girlfriend. He was buried at Foreverglades Cemetery in Belle Glade, Florida. Shortly after Waters' death, former Harvard defensive tackle and WWE wrestler Christopher Nowinski, whose wrestling career was ended by post-concussion syndrome and has since written a book about the dangers of concussions in contact sports, approached Waters' family and asked permission to have his brain tissue examined. After receiving permission, Nowinski had samples of Waters' brain tissue sent to neuropathologist Dr. Bennet Omalu at the University of Pittsburgh. Omalu believed, having examined the tissue, that Waters sustained brain damage from playing football: he went on to state that this led to Waters' depression. Omalu determined that Waters' brain tissue had developed chronic traumatic encephalopathy and degenerated into that of an 80-year-old man with Alzheimer's disease, caused or hastened by the numerous concussions Waters sustained playing football. Waters was portrayed by actor Richard T. Jones in the 2015 film Concussion.
