The Leafs don't really need anymore help on the back end, but adding a defensemen like Adam Larsson is hard to say no to, especially if the trade centres around
Timothy Liljegren, who Larsson could easily replace in the Leafs Top 4. Adding Nick Robertson to the trade would most certainly get a deal done, however the Leafs may be inclined to ask for more than just Larsson if they include both Liljegren and Robertson.
