Maybe. There has to be ways around taking the full hit on our cap.
If Boyd retires and we give him a job then next year his salary would be on our cap ala GI. Souths gave him a job at (reportedly) 300k but he was on 1 mill , so they got the balance of 700k back in their cap.
If the Broncos were to do something similar and pay Boyd say 200k we should get the residual off our cap.
Now Boyd wouldn't want to leave 600k behind but once he is officially off our cap, which he would be due to the 15 game clause, then we could back end any employment contract to keep him happy.
It's probably not as simple as that but you get the gist. Our lawyers should be able to work it out or we give the rorters a call and ask them how to do it.
