I would try everything to land OEL because IMO he´ll be or already is a very special player, and yes, i think we are indeed looking at the next 50 - 60 point swedish elite D. I like Smith and the opportunities he´ll get, but hasn´t shown anything yet so i´d take OEL over him any day of the week.
I don´t think you are over valueing granlund as he should be fantasyrelevant as soon as a season starts, and give him a year or two - he´ll be a beast IMO. His upside is just insane. He is one of my favorites, so i might be over valueing him too, but i really think he´ll be awesome.
