Johnson played college football for the University of Florida, and was recognized as the National Defensive Player of the Year.
[5][6] The Indianapolis Colts selected Johnson in the first round (fifteenth pick overall) of the 1995 NFL Draft.
[8] During those seven seasons, he started eighty-four of 104 games, recording 269 tackles, thirty-three quarterback sacks and two interceptions.
In his only season with the Broncos, he played in thirteen games, recording sixteen tackles, three sacks and an interception.
The interception came on a deflected pass in the famous "snow game" with the Oakland Raiders, and Johnson put on an impressive burst of speed to reach the end zone.
