i dont think this solves anything

LA goes absolutely no where near this.

Just freeing up cap to have a more balanced attack and fresh outlook. Arviddson, Tierney and Robertson all add fresh life into a spot where Marner sat. Similar to how we added Bunting, Kase and Ritchie where Hyman use to be.

The idea with moving on from Hyman was not committing long term to a 29 yo, and gamble by taking a chance on some younger players that were either coming off injuries, or were late bloomers.

You're doing the opposite here. Marner over the last 2 seasons (including this one in which he's struggled a bit) 81 games - 88 pts. He's 24 yo.
Arvidsson (28 yo) over last 2 seasons 79 games 45 pts. Tierney 84 games 26 pts. Marner is outscoring them both himself (pretty easily), and you've made the team older. Marner is also a top PK option/2 way player, so it's not as if you could point to improving the team defensively.

Robertson is in play to make the team next year no matter what happens to Marner - so he wouldn't be part of the equation.

I understand that a lot of Leaf fans think getting rid of Marner would be addition by subtraction, and while that might be true, I have to laugh at all these ACGMs selling him and bringing back the same D core. For me, TOR’s only real weakness is the 2RD position. I don’t think it would be necessarily to move an elite piece to upgrade that, Mrazek, Kerfoot & Holl would come to mind first.

Agreed, the only way IMO they think of moving him is if it's for a 27 or under top 4 RD, and youngish 40pt winger with upside to hit 60+ pts.

For sure, they need to get a worthwhile offer. I understand that they may need to give him a change of scenery after the season but that's a different story.
