If we make Matthews untouchable, I think that Rielly + Marner would be fair value in a vacuum.
Still not sure if Florida would bite as they have some great young wingers and they're weak on the backend and Ekblad has a higher upside than both players.
As for Toronto, I'd be apprehensive due to both players having a greater upside than Ekblads current level and the trade having the potential to be disastrous.
On a personal level, I'd almost do it to hear the bigotry fueled Don Cherry rant about the Leafs having two of the best American players in the game in Matthews and Ekblad and never having a chance without "Ontario boys"
I doubt JVR +Nylander is feasible...
