Extremely unrealistic trade. Not even in the right ballpark.

Nashville will gladly protect 4 defense with that core. If you want to peal Ekholm then you have to offer fair market value. Swap Marincin for Carrick, add a 1st, add a guy like JVR (assuming NSH doesn't just come back saying Nylander / Marner or no deal).

Just wasn't sure of Ekholm's value! You think it would cost Toronto Nylander? Would a Nylander for Ekholm trade, 1 for 1, be enough?

The cost for a top-4 defenseman this offseason, if it's not a hockey deal (ie a 1-for-1 swap like the Larsson-Hall or Subban-Webber deals), will be 3 pieces, a high draft pick, an NHL-ready or high end prospect (think Dermott, Bracco, etc.) and a young NHLer (think Brown, Kapanen, Shoshnikov, Leivo). Things obviously get a tad more complicated pre-expansion draft.
