I forgot to add a 2021 7th maybe a 5th to the Jets from Sens, the 3rds negate each other. DeMelo and Beaulieu are gonna be regular depth for this year and still possibly 4+yrs, and worth more than just Daccord who would barely play in a week and be consistently effective for the team. Sens take DeMelo back with him at $3M for 3 more years. With Brossoit going to VAN Jets would need a #2 and possibly #3 goaltender, probably be between Comrie, Daccord or Forsberg. Jets would have to pick Comrie or Daccord for the 2nd goaltending spot because Forberg is taking up the 3rd goaltending spot and would have to clear waivers, but would probably lose for nothing. Luckily Comrie already cleared waivers and can be active on the Taxi squad, Daccord is waiver exempt. Brossoit and Hamonic are 1 for 1, Harkins is a sweetener for the 5th and retained salary... but could you agree that Brossoit is an underrated valuable goaltender and that Harkins still has a lot of value... so would a 4th or possible 3rd be fair???

Jets aren't creating holes in their lineup for that. Hamonic (rental) is a downgrade from DeMelo (has term). Brossoit is a solid backup goalie while Daccord is a just a prospect that will have to fight to get a backup role on Senators next year. Harkins and Beaulieu are NHL roster players which are more valuable than low level futures (though Beaulieu is flirting with sub-replacement level play).

Next iteration of this trade, leave the Jets out of it.

It's hard to know where to start with this one. I don't think too many GM's would willingly throw away contributing roster players to downgrade to replacement level players and pay a premium to do it.

Why would the Jets pay to get worse as a team? They are replacing players with ones of lower quality than what they already have for zero in return.

That only happens when Tim Murray is driving the tank. lol
