Eichel is also not a winger. And I disagree with your assessment of Krebs as a prospect.
Mark Stone went for a 2nd and Brannstrom.
Reinhart a 2nd and Levi.
I'm starting to understand that you're either fundamentally unserious (or joking), or you just genuinely don't know much about prospects around the NHL, at least perhaps outside of the Penguins. And hey, if it's the latter, that's cool and my misjudgement of assuming the message boards of a site that was once called Hockey's Future, and was filled with content on NHL prospects, does not necessarily mean that all its regular users are well informed of same.
Let's look at a few key differences of those players mentioned, at the time of their trades:
Devon Levi -- One of the top 3 goalie prospects on the planet. Named best goaltender at the WJC tournament, and also to its all-star team. Was selected to to Team Canada's men's Olympic roster. In short, absolute top tier blue-chip stud prospect.
Erik Brannstrom -- Considered one of the very best Dmen prospects/prospects overall in hockey. Named to the WJC tournament all-star team, where he was the captain of Sweden. In short, clear cut blue-chip stud prospect.
Peyton Krebs -- Top tier prospect who would have gone top 10 of the 2019 draft were it not for an achilles injury right before the draft that made him fall. First line forward for team Canada at the WJCs and finished tied for 7th overall in scoring in the tournament. Blue chip prospect.
Sam Poulin -- Not even on team Canada WJC's shortlist in either of his 2 years post draft. Not on the short list nor made Canadian Olympic team, unlike Levi. Universally not considered one of the top 50 prospects in the entire NHL. Very likely outside of the top 75 frankly. In short, NOT a blue chip prospect at all.
But then again, Wyatt Johnson -- widely considered one of the 3 best drafted Centre prospects in the entire league, along with Beniers and McTavish -- you lumpd him in as "just another lottery ticket" with a bunch of other lower ranked/lower drafted prospects the other day.
So either you don't have the prospect knowledge, or you don't take seriously the profession and role of scouting in hockey. Because by that logic, Poulin is just another lottery ticket = to Wyatt Johnson or = to Devon Levi or = Krebs or = to virtually any other prospect.
By that same logic, the Penguins group of lottery tickets are = to Dallas' group, or = Los Angeles group or = Buffalo's group, etc.
It's a free country and you're certainly welcome to whatever opinion you want to hold; you just may find that a little self-awareness awareness goes a long way, if that's your mindset or knowledge base when choosing to post suggestions on a hockey message board.
But hey, don't take my word for it -- I would really look forward to seeing what the responses are in the trade rumours forum when you propose Timo Meier for Sam Poulin + a 2nd round pick or whatever, lol.
