I think at that type of deal that Toronto is better to hold onto those players (although the value is a bit light for Chychrun).

Kerfoot has proven to be a valuable depth piece and is producing at a pretty good clip this season along with doing a lot of other things well. & I think the Leafs are extremely high on Matt Knies and he could he up being the steal of his draft. Idk how he fell to the second round but he could be the power forward that they've been long looking for since Tucker left.

You've also added another left handed defenceman when the team already has a bunch of them. Acquiring Chychrun without including Sandin going to Arizona only holds back Sandin's development and the Leafs are very high on him. I doubt Toronto is seriously in the mix for Chychrun because of that, they may kick the tires on him just to see - but when Arizona undoubtedly asks for Sandin I think Toronto walks away

Can Chychrun play the right side?

My question too. Some dmen can't. Muzzin is perfect example. Babcock wanted him to play RD with Rielly, and he just isn't as comfortable/effective playing that side.

Capfriendly is usually pretty good marking LD/RD if a player has played both sides at some point, so I'm thinking Chychrun hasn't played much RD recently.

I feel like he’s got the skill to play the right side and a booming shot to take advantage of the one timer

It's not really about skill, it's about effectiveness. Rielly can play RD, but that extra half second adjustment takes away some of his strengths.

Muzzin has plenty of talent, underrated puck-mover, he just isn't as strong playing RD. If a player does not have much experience playing their off-side when in the minors, or early time in the NHL, then it's a pretty big adjustment.
