Leaf spent his college career with the Washington State Cougars, where he was a finalist for the Heisman Trophy after his junior year. He was selected as the second overall pick by the San Diego Chargers in the 1998 NFL Draft after Peyton Manning, but his career was shortened due to poor play, bad behavior, injuries, and struggles with his work ethic and ability to stay focused. An episode of NFL Top 10 ranked him as the No. 1 "draft bust" in NFL history.

After his NFL career ended, Leaf completed his degree at Washington State. He had legal troubles involving drugs beginning in 2010 after a Texas judge sentenced him to 10 years probation. Two years later, Leaf pleaded guilty to felony burglary and drug possession in Montana. After a suspended sentence with a stint in drug rehabilitation, Leaf began serving a seven-year sentence in state prison in December 2012. On September 9, 2014, Leaf was sentenced to five years in prison for violating his Texas probation by breaking into a home in Montana to steal prescription drugs, but he was released from prison on December 3, 2014.Leaf currently works as a Program Ambassador for Transcend Recovery Community, a group of sober living houses in Los Angeles, Houston, and New York. He also hosts a radio show and works as a college football analyst on television.
