Atlanta deserves criticism. They stunk. I was listening to Charlie Weis this morning and he was saying Atlanta is too goo not to expect to score touchdowns, even against a good defense like Philly. He said they didn't score a touchdown all the time when he was in NE (they were a ball control team back then) but that was their expectation and they were disappointed when they failed to do so. Atlanta should be of the same mindset with the weapons they have on offense.
It's OK to call a duck a duck. When something didn't go well, you don't have to sugar coat it, or sweep it under the rug. Call it what it is and fix it, or find someone who can fix it.
It's too early to call Ridley a bust. I still think he is going to a good receiver. But it is also OK if people are disappointed because they expected more than what they have seen so far. I'm sure the Falcons & Ridley aren't too happy with their performance, and shouldn't be.
I'm really not sure what you're goal is here, but it seems to me the goal is to get people to understand bad football happens to other teams so don't complain about the Cowboys when they play crappy football. There should be no excuses for Atlanta last night, and there also shouldn't be any excuses if the Cowboys start off that way.
