You start off with the premise that "all we do" is complain about a player ad nauseum. Posters like
KobesAchilles and myself post about a lot of things. Complaining about Devin is not "all we do" - and frankly I can't think of many posters who are one-track trolls in that regard. Maybe you are overly sensitive to (deserved) criticism of Devin? Or do you suggest we just stop talking about it and hope his flaws are magically cured? Or should we just accept that we're going to have a flawed roster and pretend like it doesn't exist? I'm not sure I even understand your complaint here, because it's based on a faulty premise (that there are people who "all they do" is complain about Devin, or any other player for that matter). I admit, however, I do have a decent number of people on ignore so maybe I'm missing it.
Complaining about performances that don't meet expectations are the norm here because we've been a bad team for quite too long, not just by our own standards but by league standards in general. Only the Hornets have a longer playoff drought than us. There is simply been more bad to point out than good. Even if that weren't the case, I do agree that we (humans) tend to focus more on the bad than the good, but that's because we are trying to get better, and doing so usually entails eliminating or limiting the bad things you do. "You're only as strong as your weakest link" is an expression for good reason. Debating what could be better is also where the largest variance of opinion comes in. This forum wouldn't have much discussion if it were just all of us posting "man, that Wemby is good right?" "yeah, he sure is!" There is simply not as much to discuss when we're talking about the positives. You're right though that some of that is just human nature. It's why talk radio and 24 hour "news" channels are so popular... humans feed on disagreement and outrage, unfortunately.
I look forward to when we're better and the general tone can be more positive, but even then people will still want to discuss the areas on the team that can be improved. This may be perceived as "complaining ad nauseum" but that is what fans do.
