Quoting: DougieGilmour
What team would give up an under 25 top line forward plus whatever other assets to rent Matthews? This team also has to have several million in cap space if it’s just a forward like a Vilardi who’s an RFA or on an ELC.
That's the million dollar question isn't it?
I'd imagine there are teams that want to get better now, and would gladly take a player of Matthews' caliber in their team. But it all comes down to cost.
LA is in a lucky position in terms of being one of the teams Matthews would likely sign with as a UFA, so they don't really need to spend on him as a rental.
But honestly, if a player like Matthews is unable to bring in some good young talent, then the whole market is seriously wonky.
Also, one thing to note. Matthews' NMC kicks in at July 1st, so by that point he can't be traded anymore without his approval. So, should he be traded for a package involving a solid youth guy, it'd have to be during the draft, effectively not making him a rental in the traditional sense.
If we're simply talking about teams that have assets "available", well there's Ottawa with DeBrincat, NJ with Meier or Bratt, WPG with Dubois, STL with Thomas and Kyrou and Rags with their kid line. These guys COULD potentially be in play for guy like Matthews. Ideally, the trade would involve an extension though - that opens many doors for the Leafs as well.
Honestly though, I don't think there's a scenario where Leafs would trade Matthews "as a rental", unless they are missing the playoffs next year and he hasn't been extended by that point.
