This took some math to make the money work, but this is a unique deal I think Sharks fans may be okay with if the organization was to do it. I think it would certainly be an interesting move for the organization if they were going to do something like this, but it has its benefits as well as being a pain. However, this deal does a lot for both organizations as well and in a potential deal, I think this works.
Toronto's defense is known to be a problem for the organization. The last time it was league average, the salary cap did not exist so it has been a problem for a few years. That is why Mario Ferraro is included in this deal. He will instantly improve the defense of the Maple Leafs, making them more willing to give up young players and high picks. With the three years Ferraro has left, it would hurt to lose him, but to get a return like this is worth it.
Mackenzie Blackwood would acquired from the San Jose Sharks this summer for pennies on the dollar. Since coming in, he has been nothing short of spectacular. It does feel a little bit like trying to trade a paper clip into a house like the olde videos on EBay, but that is why the return is so large. Blackwood also has another year left, making him more desirable for teams wondering about his availability.
In return, Timoty Liljegren is a good, young Swedish defenseman who could fill in for the Sharks on the backend as a stop gap, and potentially even be a trade piece down the line. He was drafted in 2017, so he's not a child anymore, but this is still a player that the Sharks could use in a productive role if they chose to. He's the kind of defenseman that could replace Ferraro in a trade.
Samsonov has to be included for the cap to work, but that is why the first round pick is included. San Jose gets another shot at a defenseman in the draft, like a Aron Kiviharju, while the Maple Leafs get multiple assets that they can keep for more than just the one postseason run. It isn't a deal that works for them for just one season.
