He played collegiately at Auburn University along with future NFL backs James Brooks and Joe Cribbs.
While he was primarily used as a blocking back in college,[1] Andrews excelled as a blocker, runner and pass catcher during his pro career.
Playing in 15 games, Andrews finished his rookie season with 1,023 yards rushing and was named to the all-rookie team.
Andrews became one of the first running backs in the NFL, along with Tony Dorsett, John Brockington, Ottis Anderson and Earl Campbell, to gain at least 1,000 yards in each of his first three seasons.
Ronnie Lott would later state that a head-on-collision he had with Andrews during a game between the San Francisco 49ers and the Falcons on December 19, 1982, was the hardest hit that he had received during his NFL career.
