Yeah those two definitely have some size. Later picks though so maybe not as much potential there. The only other recent one I can think of was Dergachyov. I think the biggest mistake with him was not getting him out of Russia. Not so much because it's a bad league, but because he was on such a good team. He might have never panned out but he would have had a better chance than plugging along on the 4th line of a stacked team. As soon as he was traded to a bottom feeder he had his best season. I don't think there was much potential regardless.Depends on what is considered "big". Andre Lee was 2019 and Sodergran was 2018.
If he makes it, Helenius is almost certainly going to be a Hanzal type with less skill, so I don't see much harm in bringing him over. I was never really enamored with him like many, he's just intriguing.
