20. Green Bay Packers: Over the past four years, Green Bay has become the home of defensive linemen with unrealized potential. Cullen Jenkins(notes) never seems to stay healthy. Johnny Jolly(notes) never seems to stay out of trouble. B.J. Raji(notes) wasn’t consistent as a rookie in ’09. Justin Harrell(notes) just never seems. Bottom line, it’s pretty damning when journeyman Ryan Pickett(notes) is the most consistent guy on the depth chart. In fairness, there’s still plenty of time for Raji. But barring a stunning shift, the rest of the guys are what they are.
