Trade 2: um what
Trade 3: Hawks laugh and block your number

Ducks Decline, That's not getting you Manson

Why would Chicago retain 300k on a 1 million dollar contract?

Why would the Hawks give up Delia is in another year would be a backup on most NHL teams for Peanuts back?

Nic Petan could be a cool pickup, but you don't send a backup goalie away for a maybe.

(You don't send a top 4 D away for a cool pickup either, but it is Bowman)

I don't know who Delia is, but if he has any value that isn't enough. There is nothing there of value.

The Manson trade isn't enough either. Bracco has value, but like high 2nd round value. Not beyond that. Ceci is neutral at best. Hollowell is a good depth prospect, limited value there. A 3rd is a 3rd... Manson is an okay 1st pairing RD and great 2nd pairing RD signed to a fair contract for term through his prime. He'll cost more than that.

you aren't going to get both Term and Amount on Marner.
There is give and take in negotiations. You know he wants to be a UFA, it takes a 4 year deal to do that. Why on earth would he take 9, much lower than what he's asking for, AND only take 3 year term.

Maybe you can convince him on lower than what he wants by hitting the 4 year term. Maybe. But you aren't going to get this.
