IMHO, there are many more than just a couple here who blame Dak for anything and almost everything that's wrong with this team. I see it on a daily basis but usually attempt to ignore it, since I realize it's done mainly out of frustration and their laziness to blame the reasons why he falters. I've never been one to claim he's a top 5 or even 10 QB, although there's plenty of those around to make up for it.
I'll freely admit that Dak relies upon his OL to play as well as possible for him to merit receiving lofty plaudits for his work. Nevertheless, I see him mostly as a better than average QB most of the time, even when there are occasional miscues from the OL. What we're seeing now, though is far more than the occasional number of miscues from an OL that is having far more than its fair share of difficulties.
I think it's more of a mistake, rather than a "sickness," to find fault with everything he does, rather than to acknowledge the other failings of the team. Those who like him and his performances for the most part are willing to allow for his faults and lack of performing at a high level when his protection breaks down. Very few QBs are able to function capably when that's a prevalent situation. Not everyone is willing to tolerate a QB who might not be "elite."
