The thing about Poulin in terms of this vote is
1) He's giving the heavy impression of regression from D+1. He's regressed numbers wise, and he's regressed in the eyes of prospect watchers because his skating has regressed. From day one, the consensus has been probable middle six winger if he sorts the skating. He sorted it and unsorted it.
Now to a certain extent he was showing upwards trajectory in the second half of his AHL season, but I'm still not sure he's back to where he was D+1 in terms of sheer athleticism. So yeah, of course he's losing votes.
2) It's real tight at the top and the other guys up there had good seasons while Poulin had a bad one. Blomqvist laid down a marker in the Liiga. POJ had a good AHL season. Pickering didn't have a wonderful junior season, and I think we're probably overrating him, but he is theoretically a physical unicorn and that gives three candidates to move past.
I think what's happening is fair. If he falls outside out top 5 prospects I'll think he's getting underrated, but right now the correction seems exactly that.
