I think it is more of a general HF phenomenon that is present across all fan-bases:
1) Players under 25 are generally overrated because they have some "ceiling" that most of them will probably never hit, and people think that a 23 year old is still going to hit this "ceiling" when in reality if he has played 300 NHL games he probably is who he is going to be.
2) People cling to draft-time opinions of players forever, especially first round talents. If a guy is 21 and former 3rd overall pick, people generally still see him in the same way they did at the time of the draft, even though we now have 3 more years of information that we should be using to update our opinions.
3) Conversely, players over the magic age of 25 are generally thought of as worthless garbage, so any trade of a 22 year old for a 32 year old is massively slanted in favor of the fans thinking the team that got the younger player fleeced the other one, as we saw with the terrible Hansen trade that people here love so much.
4) The goal of most fans here is to collect as many shiny prospects as possible, moreso than actually winning. Someone posted some hilarious quotes from Pens fans regarding Jack Skille when he was with them. The fans were LIVID that their coach wasn't giving this hot young player more ice time, and didn't seem to care about the 2 cups they won. BUT BUT PROSPECTZZ. We see the same thing with Canuck fans where some here STILL cannot get over that we did not give Shirokov enough ice time on the greatest team we have ever assembled.
I think that all of these traits common on these forums in general, and do not vary significantly from fanbase to fanbase.
