The Chicago Bears have a quarterback decision to make. And it has nothing to do with Jay Cutler entering the last year of his contract. Jason Campbell, the No. 2 QB on the roster, will be out of contract next week. It’s clear the front office and the coaching staff see value in Campbell. But how much value they see in him, and what they can afford may determine whether Campbell returns for a second season in Chicago. Last March, Campbell signed a one-year, $3.5 million deal to be Cutler’s backup. It is almost inconceivable that he will earn that much this year, especially if he stays put. The market for backup quarterbacks is not expected to be very robust, and the Bears likely will have too many other demands on their budget to invest too heavily in a player who is not expected to play a lot. With approximately $3.55 million in available salary cap space, the Bears have to choose their priorities carefully. While they likely will clear cap space before the start of free agency Tuesday, the team still will be limited in terms of what it can do. It’s possible the Bears won’t even begin negotiating with Campbell until other priorities are addressed.
