Here's the thing that I think you are not grasping here. You believe that opinions are a one way street. You can have your opinion and that's fine, but others, might be of the opinion that the view is an overreaction. That is called having an opinion as well.
No one is saying there aren't concerns and everything is perfect. It never is, but some seem to seek refuge in looking for every little flaw and waiting for the sky to cave in on this team, without giving any consideration to praising the work that they have accomplished to start the season 6-0. My sense is those looking only at the critical side are simply laying the groundwork for a future date when a loss might happen to then gleefully return here to point out how they were right about their concerns. Either that or they are just trolling. That's my opinion.
Again, and I have written this for years, I think most people are fine with posters being critical. But, the best way to approach it is to also sprinkle in some positives they saw as well. Balanced posting is usually well received and creates a reasonable discussion.
