Minnesota or Dallas
You NEED to swing a deal with either team
Detroit or Winnipeg
DET:
I continue to look at Detroit, 'cause if there'd be a bidding war, few teams can divvy up what they can, Nelson & Larkin have played well together at Men's WCs, and Nelson would be an ideal 2nd line center for this upcoming PO team that would be making the POs for the first time in, well, forever.
I also think, at his age, with Detroit's outlook in the coming years, and with it's general proximity to home, it'd be one of his absolute desired locations on the open market.
WPG:
My other guess would be Winnipeg... Not only would he bolster this team significantly in what should be a fascinating PO battle out west, but he'd surely Ok the move too (if da Peg isn't already on the 16-team list) in light of what could be a very long playoff run with regular visits from family and old UND friends.
Aside from that, even though Winnipeg would otherwise likely lose a bidding war from an assets approach, I think they'd consider taking on Mayfield as well in this move (as Winnipeg is felt likely to lose UFA DeMelo this summer) and STILL toss over young UFAs Kupari & Heinola to help us finish the season, NHL-ready prospect Rashevsky (KHL contract ends this offseason), very promising RHD Elias Salomonsson, and their 1st rounder.
I have hard time thinking even Lou would turn down something like that if Nelson and Mayfield would be on board with it!
But I might as well digress, fully aware of Lou's MO to date...
