If we are competitive and winning as construed and will definitely be better with Caleb's progress, why would they tear down assets to add to needed pass rusher that will eat assets? I don't think they will look at it as you suggested.
Now defensive assets is a different story. With the emergence of D Jackson I could see Edmunds leaving by a trade that frees up 15 mil or even J J because of what's behind him.
I still don't think a strapped cap team is trading for big salaries if they trade their best player because of Garrett money.
Turner got hurt just like Jarrett that is now healthy and playing better.
You can't plan injuries, any player they trade for could get hurt. Dayo and Jarrett both were hurt this year.
I see it more likely to go after Trey Hendrickson and try to fit his money into our Cap than trading assets to get a high level player.
Example ' trade Edmunds ( if even possible) probably getting you a third round pick, JJ ( even less likely) getting you a second round pick) re-sign Jackson and Wright and hope the money saved will put us in better position to get Hendrickson or whoever.
