@ESPNChiBears #bearsmailbag What's the latest on Briggs, is he going to retire since no one has show interest in him? — Jason Weitzel (@jw11873) May 13, 2015

Great question, Eric. Trade value is an inexact science. All it takes is for the Bears to find one team to overpay for Martellus Bennett . However, I spoke to one NFL personnel director this week who told me that Bennett does not have much trade value, in his estimation. He believes that Bennett's desire for a new contract will be a major issue if the Bears try and peddle the tight end. Bennett still has two years left on his current deal, and while I understand that Bennett is underpaid relative to his performance last year, what's the motivation for anybody to hand him new money? The new Bears front office and coaching staff needs to evaluate Bennett -- that's what the voluntary offseason program is for -- so there is no way Chicago should consider extending his contract. The personnel boss feels strongly that other NFL teams will take the same stance. I think Bennett's best move is to just play for the Bears in 2015 and revisit the contract talks after next season. I think the Bears will be much more willing to work with Bennett next offseason.Don't forget, Andrew, NFL offseason rosters have 90 players on them. That number is trimmed to 53 in Week 1. A little less than half of the players attending the Bears' voluntary offseason program will not be around in the fall. But you are correct, there are a ton of linebackers to choose from -- Jared Allen Christian Jones , Jon Bostic, etc. I can't see all of the names I just listed making the team. There are expected to be tough cuts at the end of the preseason, and some will come at the linebacker position. I don't expect as many surprises at safety. Antel Rolle and Ryan Mundy appear to be in good shape on the first-team, with Adrian Amos and Brock Vereen vying for the backup roles.The last I heard is that Lance Briggs still wanted to play. He was close to signing with the San Francisco 49ers at one point, but I heard the two sides were unable to agree on the money. I assume that if Briggs stays patient and keeps himself in good shape, he will find a job in the near future. But Briggs is going to have to take a substantial pay cut from the $5.5 million in total compensation he pocketed from the Bears in 2014. That's not easy to do for such an accomplished player. But that is how football works. Unless Briggs decides to hang it up, I expect him to find a new team and be in camp, somewhere.
