Habs would lose big time on the long term with that OEL trade. Add Duclair and a 4th round pick in 2018 and that would be more of equal value. Only thing is; Arizona won't want all those additional contracts to pay (they are on a low budget).

Furthermore, Bennett won't go anywhere. Calgary will keep him and send off Backlund as soon as his contract ends. I would ask for Backlund (If he signs a prolongation contract right away) and offer something else instead of Lekhonen
