I like it.
I'd have to wonder about Rhodes ability to cover man at the next level. In actuality, taking Rhodes in the second and moving him over to free safety might not be a bad idea. The kid is huge (6'2", 217 lbs.) and has shown he's an effective press cover corner. I think his ultimate upside is free safety at the next level where his speed and size would translate well and you wouldn't have to worry about that initial backpedal burst (or lack thereof) at the CB position.
I'd also possibly switch Lattimore for someone like Monte Ball, who, if Hillis isn't retained, would be an effective downhill/in-between the tackles type runner.
A flyer on Hunt wouldn't be a bad thing either.
And with Armstrong, you could get a menace or you could get a Vontaze Burfict, who is playing really well for the Bengals.
