Lewis pleaded guilty to obstruction of justice in connection with the stabbing deaths of two men in 2000. The following season, he was named NFL Defensive Player of the Year and led the Ravens' record-setting defense, which established a 16-game single-season record for the fewest points allowed (165) and the fewest rushing yards allowed (970), to victory in Super Bowl XXXV. Lewis also became the second linebacker to win the Super Bowl Most Valuable Player Award, and the first to win the award on the winning Super Bowl team. Lewis won his second Defensive Player of the Year award in 2003, becoming the sixth player to win the award multiple times. After a triceps tear that sidelined him for most of the 2012 regular season, Lewis returned for the Ravens' playoff run and earned his second Super Bowl victory in his final NFL game. On February 3, 2018, the fifth anniversary of his final game, Lewis was selected to the Pro Football Hall of Fame in his first year of eligibility.
