I think that it would take Rakell and Manson at the very least -- maybe a swap of second-rounders, too.

Manson + 6th overall for Nylander, or
Manson + Steel for Nylander. He is gonna be costly.

not enough

I really don't. I know people are down on Rakell but He is NOT that much of a downgrade on Nylander by himself and he costs a little more half as much. Lundestrom is near NLC ready as a depth 2 way center who can help sooner rather than later(as a pick would be). The added savings in cap space allows them to further shore up their depth.

Can't see the Ducks move the 6th overall unless theyre trying to move up. I went with Lundestrom as I thought he fit Tors needs more than some other guys. Jones is LW. Steel is a more offense center while Lundestrom is a recent first rounder who projects as a 2 way forward. Hes waiver exempt still and gives some center depth. Id probably offer a pick to make up the value between Lundestrom and Steel, which isn't likely very much, to get the deal done.

Not trying to be rude, but the value here is just not close, imo. An okay #4 Dman with two years left and a prospect who likely tops out as a defensive 3C for a top line winger? Doesn't seem like a very even swap.

It's not rude to have an opinion. I disagree with your evaluation though. Manson has been on the Ducks Top Pair for years. He is a complimentary D man who can handle Tough D zone assignments, PK duties and high end competition as evidenced by his time with Lindholm. The last 2 years have been bad for ALL Ducks players. I think calling him a okay #4 is underselling him. As a Ducks fan, I am only moving Manson IF he brings in a top end talent. If hes not enough to get that conversation started Id much rather keep him.

Playing in a particular role in itself is not an accomplishment. Who else could they have reasonably played above him the last while? He does get the tough match-ups, but he's handled them pretty averagely over the last couple of years (good this year, not so good last year) and considering his defense is the big selling point for him, anything short of 'great' in that category isn't likely to fetch a top end talent. He's pretty good at shutting down the opposition and he's tough, but that's really about what you're getting. Doesn't contribute much offense, not great but not horrible possession-wise... Maybe 'okay' was a bit harsh, but he's not more than a #4 Dman, imo. Having said that, I would like Manson on the Leafs and have defended that statement against fellow Leafs fans in the past. But that is an astronomical price for what he is.

Aside from all of that, though, there would be legitimate question as to whether the Leafs protect Holl or Manson in the ED. Manson would have one year left whereas Holl would have two at half the price. If Holl is replicates his quite good season, he would probably be the more reasonable choice, meaning the Leafs lose Manson after one year. There are other outcomes surrounding that, of course, but none of them are really ideal.
