Ahman Green is the NFC's leading rusher with 681 yards.

You want old school? It doesn't get much more old school than Packers vs. Bears. Sunday's showdown between the top two NFC Central teams is the meat-and-potatoes kind of matchup that conjures up the deep bellows of NFL Films announcer John Facenda. The turf had better be in tip-top shape. With bruising offensive lines paving the way for the teams' power running games, Ahman Green and Anthony Thomas figure to do some damage to the Soldier Field sod as well as the defenses.
