He played college football for the Houston Cougars and was selected by Seattle in the third round of the 1994 NFL draft.
On December 30, 2000, Smith carried the ball a then-NFL record 40 times for the Dolphins in a wildcard playoff game against the Indianapolis Colts.
After high school, he attended Northeastern Oklahoma A&M College and then the University of Houston on scholarship for his final two years.
He was drinking and driving prior to a car wreck that left teammate Mike Frier paralyzed from the neck down.
The prosecutor noted that Smith had drunk at least five beers and six-and-a-half ounces of Scotch shortly before his car struck a utility pole.
