I like every trade that you have presented here. (Not sure how the teams involved would feel about them but, I certainly dig it).

I think that OTT/TOR trade is great.

OTT gets a RW where they are starved

TOR gets an analytics darling RHD, Dubas's wet dream

Flames really have no need for LW's or LD's so it doesnt make sense

Giordano is out 4-6 weeks..

Why do the Leafs want an injured rental in Hamonic?

I don't like the Ducks trade either, giving up a decent RHD for a 4th line forward?

Vegas can't take on Barrie's salary so that's not happening.

I like the Ottawa deal but I have to assume they want more for Demelo.

Not sure where you heard 4-6 weeks from. Also Hamonic is on IR too so i don't know why you would trade for him. Brodie can play the left side so there is no issue there. As for Dermott, he is an RFA in the summer so do Flames just not qualify him? He's not better then Gio, Hanifin, Brodie, or Valimaki. He might challenge Kylington for the 7th spot but that's about it.
