I think it's still a damn good defense, but I think you're going to play a lot more Jaylen Mills CB2 snaps than we'd like. The idea of him playing box safety to man up tight ends in certain looks to let other guys do other shit was really appealing, and while the fact that he's not a disaster outside is a definite value add, I think he's always looked like a better safety (especially shorter) than outside corner and he's spent his whole time playing out of position because they needed him to.
He even posted this offseason when nonsense rumblings about "safety depth" were happening that he considers himself a safety, and they've made a point of trying to get him in the middle when they projected to have other options outside.
