Career Years: 1989-1998
Career Lowlight: Sent to rehab in 1995.
Dubbed "the best offensive line prospect ever" by a 1989 Sports Illustrated cover story, Mandarich should probably have been called "the biggest juicer ever." He has freely admitted to using steroids throughout college to boost his draft status, although it was alcohol and narcotics that derailed his pro career after he was drafted No. 2 overall by the Green Bay Packers ahead of Hall of Famers Barry Sanders and Deion Sanders. After falling out of the league by 1991, then going to rehab in 1995, Mandarich actually returned to the NFL and had three decent if unspectacular years for the Colts before retiring due to a shoulder injury.
