NFC North Stock Watch

FALLING 1. Secondary play in Chicago and Minnesota: Between the two of them, the Chicago Bears and Minnesota Vikings have maybe one or two defensive backs who should be considered 2012 starters heading into the offseason. Bears cornerback Charles Tillman qualifies, and perhaps Vikings cornerback Antoine Winfield will as well if he returns healthy from a fractured collarbone. Otherwise, the Bears and Vikings need a serious overhaul to their defensive backfields.
