Though a standout prospect at football, Johnson's early life was plagued by gang crime and legal troubles.

In eighth grade, he spent nine months in a California youth facility after being arrested for possession of marijuana, cocaine, and a concealed handgun.

After the 1994 college season, Johnson helped lead the Trojans to a win in the 1995 Cotton Bowl Classic, after which he was named the game's Most Valuable Player.

While in college, Johnson appeared on the TV show Coach, as a player eligible for draft in the upcoming season.

He flatly refused to be recruited to the fictional "Orlando Breakers" team for coach Hayden Fox, stating he would go to Canada to play first.

[12] Within the confines of Sunday NFL Countdown and Monday Night Countdown, Johnson invented a segment called C'mon Man!, which allows each panel member to pick a moment in the last NFL week "revolving around either the play on the field or unprofessional behavior off it" that one might consider, on some level, either inexcusable or downright laughable.

He has also been an analyst on several ESPN telecasts, including pre-game shows on Sundays and Monday nights, and some radio work as well.

On January 23, 2011, Johnson was not on Sunday NFL Countdown for Championship weekend because his mother unexpectedly died.
