Off-season you mean? You're not really thinking the Leafs (or Preds) would do this right now, are you? If this is a trade proposal for pre-deadline, it's asinine.
Leafs trading away (arguably) their top defenceman, who has been there since before the lottery pick days, with the team's best chance to go deep in decades, and you thank him for his service by shipping him out for an upgrade with less than 20 games left in the season? Then pray that Ekholm, after clearing quarantine fits in with his new partner, system and team before the playoffs start.
I'm sure Reilly's current teammates would love it too. Can't speak to Nashville fans/team but the Preds are in a playoff spot right now so for similar reasons.
Asinine.
