On top of the obvious 2/3 (Manning, Harrison, and if Urlacher keeps it up)
Kreutz should go, best Center in the league for the last several years
Rueban Brown stand a chance someday, hard not to with all those probowls.
Glenn maybe someday
Bob Sanders if he stays healthy may someday as well, he's a hell of a player
Freeney
Tait maybe someday
Muhammad, outside chance but probably not
Hard to tell with the backfield from Chi, Jones, Grossman or Benson. Give it a few years to play out.
