3. Green Bay: Someday in the near future, NFL people will talk about how the Packers linebacking corps is like some four-headed nightmare. With Nick Barnett(notes), Clay Matthews(notes), Brad Jones and A.J. Hawk(notes) (who is almost an afterthought in this group), the Packers have the best combination of great tacklers against the run and potential pass-rush stars. Throw in the fact that Barnett is the only one older than 26 (hes 29), and you have the makings of something marvelous. Matthews was terrific all season, and Jones was a late-season revelation with all four of his sacks coming in the last five games.
