Ryne Sandberg believes that performance-enhancing drug users should receive two- to three-year suspensions.

"The message can't get much clearer that drugs don't belong in baseball and don't belong in sports," Sandberg said. "Every time baseball takes a hit, it is another step backwards in what needs to be done. I personally think the punishment and penalties need to be much stiffer than that. If you have a guy who tests positive and he has to sit out two to three years, that is a little different ballgame."

The current system calls for a player to be suspended 50 games for a first positive test, 100 for a second and a receive a lifetime ban for a third.

Sandberg, who won National League MVP in 1984, made playing the game the "clean way" a theme in his 2005 Hall of Fame induction speech.
