I used to read here daily, and post regularly. Now I read rarely and post almost never. I'm in no way special, but here's my long take. Probably too long to care about.
1. There's nothing to discuss in the off-season. When I started posting, the Pens were up and coming and the playoffs were an aspiration instead of a certainty. Back then, I remember the summers getting a little chippy because there's not enough to discuss. You can go around and around about line combos but when there are no games being played, your theories don't get tested. People who disagree get testy because there's no evidence to settle disputes.
Now the Pens are good enough that the same attitude is in effect. They'll make the playoffs in a walk and no one considers it especially interesting. The questions about this team are all about how they'll do when crunch time comes. It's not possible for the regular season to offer any evidence in this regard, so people who disagree about whether the Pens will win a Cup with Fleury in goal or Bylsma behind the bench spend 82 games getting snippy with each other. Boring!
2. Lack of nuance, profusion of false dichotomies. The glass-half-full types divide the world into 2 camps, the Realists (themselves) and the Grumpy Cynics (all those who complain about everything). The glass-half-empty types divide the world into 2 camps, the Realists (themselves), and the Fanboys. The best thing about this board used to be not just the range of opinion about the team and what should be done, but the widespread recognition that opinion exists on a range. Now it's just a bunch of people talking past each other, and this thread is a fantastic example. Posts like "I can't wait to bump this when the Penguins get knocked out of the playoffs" are useless. Complete waste of space and time. Everyone, everyone, including the "Fanboys", is nervous about how things will go in the playoffs. If the Pens win the Cup, it doesn't mean the criticisms about the play of Orpik and Adams were invalid -- those guys have been putrid. If the Pens don't win, it doesn't mean Shero or Bylsma or Letang or Fleury aren't capable of doing so ever again.
3. Reading from a script. Someone said it's not that they lose, it's how they lose. Nope, that's not the problem with the boards. When the Pens play badly and lose, no one's going to object to people analyzing the problems. The problems on this board come when the Pens win, even in dominant fashion, and still the response you see in the PGT is a bunch of, "that's nice, but Bylsma is still an idiot and he will blow it in the playoffs because GLADAMS." I'm all for having a measured response to both wins and losses. Criticism isn't out of bounds even in a dominant win. But there are a few very vocal posters around here who seem to have a script, and they are BY GOD going to stick to it regardless of what happens on the ice. Boring! There are still some good posters, but they are getting drowned out by people who see everyone and everything with the team as love 'em or hate 'em. In truth, Bylsma is a very good coach who has at times had difficulty making tactical adjustments against certain kinds of teams. Letang is an outstanding defenseman who is prone to mental errors and poor decisions, and who was likely hurt by a lack of training camp time. Shero is one of the top GMs in the league but has made a number of decisions that didn't pan out well. You just don't see enough of that kind of analysis in the vast middle ground between "Letang for Norris!" and "Trade Lestink!"
4. It ain't a computer game. There are human factors involved. Many people saw Bylsma fail to put Iginla on Sid's right wing and have thought no more deeply about the situation than to say "Bylsma is a moron." From the outside that makes sense, but is it possible that Sid told the coach he wanted to keep Dupuis? He has a distinct preference for playing with fast wingers. There were rumors to that effect. Is it possible that the situation was more complicated and nuanced than Bylsma being a moron? (Note: Bylsma is not a moron. Likewise, Orpik's performance has been totally undefendable in my view, but he wears an A. You frequently see him slammed for "do as I say, not as I do" leadership. A lot of that's probably fair. But gosh, is it possible that people with actual behind the scenes knowledge find his leadership in the room valuable? Is it possible that his departure would leave a bigger leadership void on defense than the posters here realize? Well, I don't know. And neither do most of you, I suspect.
Wow, look how much I wrote. Sorry, I better stop now.
