DETROIT -- The moment Ndamukong Suh snapped and stomped on Green Bay's Evan Dietrich-Smith, he added fuel to the discussion of where he ranks among the NFL's dirtiest players.
It's also expected to lead to a suspension by the NFL for the Detroit Lions defensive tackle.
Suh is in the spotlight for his actions, but players have crossed the line since the league was born and probably always will do so at football's highest level.
Four-time Super Bowl winner Matt Millen says Suh wouldn't miss a down if he slammed his foot on the arm of an opponent back when Millen played linebacker with the notorious Oakland Raiders and won championships.
Millen believes players regarded as dirty are usually people you love if they're teammates, hate if they're not.
