Welcome back to our offseason series of Four Downs. We'll be reviewing each division one-by-one, looking at each team's biggest hole going into free agency as well as the most important players who may be on the market (provided they aren't franchise tagged or re-signed before March 5).
Chicago Bears
Biggest Hole: Secondary
Chicago's secondary is the team's only position group hemorrhaging key starting talent this offseason. Safety Adrian Amos and star nickel cornerback Bryce Callahan are both due an extension this spring, but with a dire cap situation due in part to the Khalil Mack trade-and-sign, the team does not have room to keep both defensive backs.
