for some reason it seems like a classic move that will result in us not getting any significantly better in the short term. immediately play the 18yr old (which i know hes fully capable of and will do), d-corp gets younger without adding any vet d, play him on the top line and feed him to the wolves and pair him with an ekblad who cant skate well enough to cover his tracks. dahlin, in this completely hypothetical and dream scenario, should start on the 2nd at most and play with a seasoned vet who can be a mature guiding force (not in terms of play necessarily) and help cover him defensively as dahlin will surely carry the puck through the zone and engage a lot within the offensive zone. at least dahlin can skate and play some (surprisingly physical at times too) defense.
with how the draft lottery is set up now it really is a complete crap shoot. anyone in the top-7 or the top-10 really could easily wind up with it. i wouldnt be completely focused on dahlin, although he is definitely the prefered top pick, but winding up with #2 and getting a big goal scoring russian rw like svechnikov, someone who could be in the mold of tarasenko or kucherov, would do absolute wonders and would give that top line a legit scoring threat. making the top line one of the best in the league.
