These days, you need three good cornerbacks to defend the multiple receiver looks that are so popular around the NFL. It also helps to have some variance in size to defend the taller outside receivers and the shorter, shiftier slot guys. Matching up with tight ends on occasion requires a corner with toughness and strength.
The Chicago Bears, on paper at least, have three guys that they should feel comfortable with.
When trying to determine what the Bears will keep at cornerback, from a numbers standpoint, for the final 53 man roster, we have to look back at what head coach John Fox and defensive coordinator Vic Fangio did in Denver and San Francisco respectively.
