No we can't. Losing a whole 2nd pair D unit does not just get filled in with random "pieces around him".Edmonton doesn’t have Rasmus Dahlin. We have one of the top 3 defenseman in the world, and he is young and a workhorse. We can fill in the pieces around him.
To play along with Der Jaeger's idea though, I think it would be more like this -
Cozens
(two FW prospects)
Jokiharju
Comrie
at least a 1st rd pick and probably another
Edm gets a young promising FW from within the same hemisphere, whichever prospects they like, a RHD they need, a hometown goalie, and picks of course. The cap works out in their favor and we give up the farm.
