No, you missed my point and I may have done a bad job explaining it because I was on my phone and dealing with a 60-120 second refresh.
My point is that Marner is one of many expensive contracts which block Toronto's ability to add players they actually need. Scoring is a non issue in Toronto, they have 140 GF, good for 10th in the league (tied with Nashville at 45 GP and Anaheim at 47 GP vs Toronto's 40). Toronto needs secondary scoring, a top 4 RD, a solid backup goalie, and players who play with an edge from my perspective. How do you achieve all that?
I willy nilly put in Chychrun without thinking about returns, that was a mistake, exclude that part from my post.
You can get Chychrun to Toronto without moving Marner, maybe play Muzzin on RD next to Chychrun, but you still have a backup goalie, forward depth, and lack of physical playoff players issue, on top of a flat cap.
