I wouldn't touch Jarretts, his contract can be cut after this year with little dead cap.
For now, I'd keep JJ and hope he regains his feet. Wright was a great FA find, but not sure his coverage was anything special. 62% passes were completed on him. Like CJ-GJ, he was a liability.
Id restructure Thuney, not Jackson though, they need to have flexibility to cut players if needed to and RG is easier to find.
