I feel like the Leafs have loaded up on so many picks they could make a fairly competitive pitch to any team in the top 3 to trade down if they really wanted to do that. Let's say Edmonton has a top 3 pick and doesn't want Matthews, Laine, Puljuhaarvi, they could drop to 4 to take Chychrun and pick up a few picks from the Leafs for their troubles.
Yeah, I'm actually hoping that Edmonton gets a lottery pick. Especially if the Leafs don't. This is the only team that I think may be open for business. I can definitely see them swapping their 3rd for the 4th to obtain Chychrun. Also, the Oilers swapping their first overall for 2nd or 3rd, although a long shot, isn't completely out of the question. If you're a lottery winner and offer your 2nd or 3rd and a decent pick or prospect for their 1st, maybe they do it. If you offer the 4th, you'll have to add a pretty significant prospect or player, but it may just be worth it for Matthews.
So, for example, if you're the Oliers, do you want to walk out of there with Matthews or Chychrun and Gardiner? (just an example....don't flip out)
