I realize I may be jumping the gun a little here, seeing as we don't know exactly who is going to be running/setting up the offense, but info is info..
I don't see the bears keeping Bell, Bowman, Campbell, Nolan, or Mare. DJ Moore is/was a Lovie favorite, and could very well be allowed to go as well. A. Okoye, McCown were let go last year as well, unlikely the bears keep them. Rachal will probably be allowed to walk due to the way his season ended. Collins and Allen are both rather far down the depth chart, I view them as likely to become free agents.
Could Izzy be allowed to walk due to cap concerns? Also, how much would Scott and Spencer cost, IF they were deemed worthy of retention? Are there persons that I am wrong about being allowed to walk? comments? questions? concerns? Insults? (probably don't need much help with that last one)
Hmm maybe if Tice is gone Rachel may get a 2nd chance? Fresh start n all? If say its unlikely but plausible
