They were a good team and he put up good point totals. I don't think what I said is wrong. Being the highest scoring defenseman doesn't mean he's the best offensive defensemen prospect to come out of the league, and there actually isn't such a great track record of Liiga producing a lot of good defensemen.
I'm comparing him to Lundkvist because I view them as having similar limited upside. Average size, some offense, some defense, good hockey IQ, good skating, but no part of their game will definitely make them a top four defensemen. I think both have second round level upside, but will go in the first round due to having good draft seasons. In Lundkvist's case, he went 28th. I think Heinola will go somewhere in the 15-25 range, which is a little higher. He also played at the WJC20, and played well there. Lundkvist didn't get that boost in his draft stock.
Similarly to Heinola, Lundkvist also had a bad WJC18. I'm not saying they are the exact same player or that I'd say the best comparable for Heinola is Lundkvist, but I don't want my team picking two players who project similarly in the first round in back to back years. I don't like taking one of these types of players to begin with. I think all these players are projects, so the "higher floor" mantra for why some prefer these types of players doesn't make much sense to me. You can find many bottom half of the lineup players in free agency every offseason. Why would you try to draft these players instead of players who can be in the top half of the lineup players? You can't acquire those players as easily.
