The Bears will eventually fade like KC once Caleb gets paid. Unless they can hit on draft picks every time at the right rythem. When I suggest trading a beloved Bear star, it is because there are rising younger players at their position and while their value is still modestly good for our beloved, we could get more in return now. The Bears need 2 starting caliber DTs, one DE, one or two S, one or two LBs, and a CB. They have extra WRs and maybe a TE that can replaced with younger/cheaper.
3 or 4 defensive starters might be draft picks, but they will also need some veterans that fit. Not much in the bank unless they can find some teams to trade with.
Its just my thought on how to logically do this. Kmet is one of my favorites, so I would love him to retire a Bear. But sometimes tough decisions need to be made.
