To be honest, since the franchising of Matt Forte, the Bears don't have many key free agents to retain. Most of the players on this list are average starters at best.
At the same time, with their substantial cap room, the Bears can decide who they want to keep based solely on their ability to play football, as opposed to being slaves to a cap number.
Nonetheless, here is the value of every free agent on the Bears roster, should they hit the open market.
Roy Williams: $1.3 million (estimated)
Williams made a few plays for the Bears this season, but he has never quite lived up to the hype of his draft status.
Perhaps he would be more effective with better playmakers around him. Also, the injury to Jay Cutler did not help his numbers, but he is not going to see a lot of action on the open market.
If anyone offers Williams anything slightly above the veteran's minimum, he should take it.
Amobi Okoye: $2.8 million (estimated)
Okoye enjoyed a bit of a resurgence with his move to Chicago. Okoye, the youngest player to ever enter the NFL draft, never quite panned out while playing for the Texans.
Chicago explored locking him up in the middle of the season, and would figure to attempt to retain him, and Okoye should get a significant pay raise.
Brandon Meriweather: $2 million (estimated)
After bringing in Williams, Meriweather, Amobi Okoye and Vernon Gholston, the Bears' training camp looked like a draft-bust convention this past August.
After a bitter ending with the Patriots, Meriweather proved himself to be at least a competent player. With such a demand for safeties, Meriweather will get a healthy offer from a safety-needy team.
Caleb Hanie: $600K (estimated)
Once regarded as one of the better backups in the league after an inspired performance in the NFC championship game, Hanie's play in relief of Jay Cutler may have cost him a career in the NFL.
At this point, the most he can ask for is a chance to compete for a No. 3 job in training camp—other than that, Hanie's NFL career may be over.
Israel Idonije: $2.4 million (estimated)
Peppers gets a lot of the credit for the success of the Bear's defensive line, but Idonije is one the more unheralded cornerstones of one of the best run defenses in football. He also brings some value as a pass rusher from the three technique.
He earned $2.5 million a season ago, and I expect that number to stay about the same, though it may perhaps take a bit of a dip because of age.
Tim Jennings: $1.7 million (estimated)
Jennings started his career as a core special teams player, but he has elevated his play to earn time in specific defensive packages and has proven his worth.
Jennings is a real fluid guy with great quickness to make up for his lack of size. He fits well as a zone defender in the Bears' system and deserves a considerable pay raise.
Matt Spaeth: $2.2 million (estimated)
An above-average blocking tight end, Spaeth should make somewhere close to the amount he made last year. He is not much a receiving threat, caching only seven passes for 50 yards last year, so there will always be a ceiling on how much he is going to make.
Craig Setlz: $900K (estimated)
Seltz is a nice special teams player who provides depth at safety. Such players usually make somewhere near the minimum.
Being with the Bears for four years, Seltz is comfortable with the system and is likely to stay in Chicago.
Josh McCown: $1 million (estimated)
McCown was an emergency replacement for the inept Calib Hanie, and proved himself to be at least competent, earning himself another year or so in the NFL as a backup.
With a shortage of backup quarterbacks in the NFL, McCown's value is more than his actual talent, and should get a bump in pay after his performance.
Kahlil Bell: $1.1 million (estimated)
After Matt Forte went down toward the end of the season, Bell came in and did some nice things in his place, especially in the Christmas night game against the Packers.
He is not going to be a prized free agent, but he earned himself a pay raise with his play at the end of the season.
Kellen Davis: $1.5 million (estimated)
Davis took over as the starter at tight end, but because Mike Martz's offense does to utilize tight ends in the passing game, his impact was limited. In a new offense under Jeremy Bates, he could produce at a much higher level, but that must be proven before giving Davis a lot of money.
Zack Bowman: $800K (estimated)
Bowman has developed into a solid player for the Bears and earned himself a starting job just two seasons ago, but his play has since dipped, killing his chances of making starter-level money in the NFL.
He won't generate a lot of interest in the open market.
Corey Graham: $1.7 million (estimated)
Graham fills a lot of roles for the Bears, both as a great special teams player and as a nickel corner. He is going to want a significant pay raise and a bigger role in the defense.
Whether or not he returns to the Bears depends on if the Bears are willing to give Graham what he wants.
