I got a shortlist of UFA dmen that I'd be happy to go after and where I think they'd fit. Kovacevic has been on my wishlist for awhile. He seems like a good bang for the buck pick up even if we need to overpay a little.
Anyways, here's what I got so far.
top pair: ekblad, pettersson, gavrikov (facing top comp/minutes and doing well or breaking even)
top 4: kovacevic, orlov, burns, chychrun, dumoulin, maatta (not sheltered and playing well in their roles)
bottom 4: chisholm, scmidt (overperforming sheltered minutes)
