This isn't just directed at you Pavels, but it's the most recent post I've seen that has it, but I'm curious about all of the reasons behind keeping Quincey over Smith. Q easily had a better year this year, but he's older, more expensive, and is only around for another year before we have to renew his deal - which likely means another raise.
Smith is younger, will still be cheaper after his RFA deal, and had a second consecutive playoffs of upping his game. Also, Quincey has likely maxed his trade value right now, and Smith - on his next, cheaper, short deal before he hits his UFA years, could be a better trade piece in a year or so. And I don't think swapping one for the other appreciably hurts us on the ice next season.
If (big if, considering the past few summers) we can land that big ticket UFA we want, I'd look at running something like:
Kronwall-Smith
Dekeyser-Green
Ericsson-Marchenko
Jensen (he's out of waiver exemptions now, right?)
Ericsson can anchor that bottom pairing, Smith has looked promising with Kronwall in the past, and I think we maximize trade values as we rework our D.
