I dont think a Zaitsev trade taking back bad salary in return will work for Toronto.
Considering Z plays our most needed position, we arent gonna move him for deadweight salary up front.
I could see the move being one of two types of deals...
Either a small 1 for 1 trade for a cheap LWer with a big body like a:
Zaitsev for N.Ritchie OR Zaitsev for Micheal Dal Colle OR Zaitsev for Lawson Crouse
Or it could be involved in a bigger trade where the leafs get their top pairing d man like a:
Trouba for Zaitsev, AJ, Kapanen OR Ekblad for Zaitsev, AJ +....
In this deal Winnipeg would probably need a capable top 4 RD back when they lose Trouba.
