Did some of my own digging right now, but I do like the Swede theory from the Wings.
Malmstrom seems like a bit of a reach in the fourth round.
Larsson I agree doesn't have great numbers, but they could have seen something they liked in the his style. Goalies develop in funny ways. I will never question a late round flier on a goalie.
Elfstrom gets some praise both for his foot speed and his shot. Sounds to me a little like a swedish Pulkkinnen. They like his big body too, and he actually uses it to his advantage.
