If Kadri and Zaitsev are traded for pure cap space only, we would have 14.3 million for Marner and a D man.

Horton LTIR... everyone knows this. come on.

1. Miller - I think you are right. he is worth a 4th. IN a bubble no he is worth a 2nd and 3rd and change. But this isnt a bubble. Vegas needs cap relief. Marleau cost an arm and a leg to get out of 1year. Subban was given away, as a superstar for 2-2nds. SO that severly lowers Millers value just because of the cap relief vegas needs.
2. Brown is gone. Trade him for a 2nd or 3rd to a dumb GM like the oilers
3. Ziatsev is gone, trade him for a good asset to a dumb GM who missed signing Myers to a 7x7 deal
4. 85% sure Bracco is not NHL Ready. Dispite looking good his corsi was awful and he got caved in, in the AHL at times.
5. Horton on IR
6. Maybe a new backup
7. Maybe a veteran on the 4th line. THis years Tyler Ennis. Maybe Ty Rattie

As the summer goes on my mind keeps changing on Nylander and mostly it's because of the numbers being thrown out of the Marner deal.

Before the season ended I came to conclusion that ya just gotta keep Nylander despite how much you may want to trade him because of the season he had...and trading pennies on the dollar is not really too smart.

What may (already is changing?) change for Leafs management is...how badly do they want Marner on this team? Because having him comes at cost higher than just the 9-12 million range he's rumored to get.

It means trading players management did not want to based on any number of things.
Leafs just can't bring back last year's D, and while some of us here think Lilegren, Sandin and Rosen (I'm looking at you @Laudan , kidding) are going to play significant minutes, that would be a mistake.
Definitely for the first two D mentioned, Rosen is probably more prepared for some minutes.

If keeping Marner is the decision, then perhaps trading Kadri/Nylander becomes the way to add a top RHD. Does this make the forwards weaker? Yep...but this team has been top heavy and so far it has not worked.
