Looks like the Steelers are going after Dre Kirkpatrick or Logan Ryan.
Logan is likely to outprice himselff from the Patriots liking. Pats signed Stephon Gilmore from the Bills today for 14 million per and reports are they're considering trading Malcolm Butler for Brandin Cooks and a first round pick. I can't see them rostering, never mind paying for two #1 corners, so I'd expect another shoe to fall.
I'm assuming once the dust clears Butler will play a year on his RFA Tender so he has more control next year and gets paid like a UFA. I don't see many teams giving up a #1 and paying him as a top 3-5 CB. New Orleans is unique in that they can just return the 32nd pick that New England sent for Cooks, and then bundle a 3rd in... but the wild card there is they also have to lock Butler in for at least Gilmore money... I see this making more sense for all parties (excluding the Pats) next year.
