I don't know that its blissful ignorance - i'm a fan of the team. I root for their success. I go on a site like this because there's at least a higher percentage of level-headed discussion vs. something like twitter where its just everyones hot takes arguing. I don't think saying you have concerns about depth or something is inherently pessimistic - but basing your concerns about cornerback depth for example - because we didn't do well in a preseason game isn't fair to the players and coaching staff. I have no idea what Dorian strong is capable of, and i don't know that i got more insight based off of that preseason game.
The 24 hour news cycle, and the NFL's insistence on daily news amplifies the importance of practice games that truly don't match the game-planning process, or the physical intensity of actual NFL football. Every year "the game slows down" for all the QBs in the 1st round, followed by them playing actual games and it speeding back up and punching them in the mouth. The player you are today isn't the player you will be come september, october, november, all the way to february. Just my 2 cents in trying to try and be a bit level-headed with player criticism, and expectations.
