10. Rashaan Salaam
There are several running backs on this list who regressed badly in their second season. Salaam is up there with the worst of them. The Chicago Bears drafted the 1994 Heisman Trophy winner. But he became one of their worst draft busts. To make it worse, he showed a lot of promise his rookie year.
After rushing for over 1,000 yards and 10 touchdowns in his rookie year, Salaam regressed. His sophomore slump saw him achieve less than 500 yards with a mere three touchdowns. Finally, he only played 17 games in total for the Bears after his rookie year because he liked marijuana more than football.
