I'll be honest, this really shouldn't be a difficult concept to grasp, I shouldn't have to break things down for you, but since you seem to be having a lot of trouble with understanding things I'll do just that.
The very first post in this thread is looking at QB rankings as ranked by ESPN.
Stafford is ranked 9th. Last week he was ranked 8th. There's a little red arrow pointing down next to his name under the "trend" section. That's trending down, just so we're clear.
By the end of week 3, Stafford was ranked pretty high, higher than 8 and certainly 9. The last two weeks he hasn't played as well as he played in weeks 1-3. Even if he played pretty decently against the Hawks, it wasn't as good of a performance as he had weeks 1-3. That's why he's ranked 9th currently by ESPN, which is what this thread is discussing until it got quickly derailed to talk about who we would build a team around.
I said that while I am not worried about Stafford, I can understand why the 8 QBs ahead of him in their rankings are there, although I'm not really sure about Prescott, and honestly I think Jackson rose way too much, but whatever. Stafford is trending in the wrong direction by their chart, because the last two weeks he has gone down in their ranking. I don't know about you, but I generally think that when a player drops in the rankings that's going in the wrong direction, I would prefer they go up.
You can save the straw-man arguments as well, I'm not expecting him to go out there and throw for 5 TD's and almost 400 yards every game, I never said anything remotely to that. I said the past two weeks he has missed some throws, and left plays on the field, which is just an objective fact if you watched the games. That is why he's dropped in their QB rankings and at this point, it's hard to argue against their logic because those things have happened, he played better in weeks 1-3 than he did weeks 4 and 5. That doesn't mean he's played like absolute shit and is the worst QB in the league or anything stupid like that, it just means that he played really well in the first three weeks and not as well in the last two weeks. That should not be a difficult concept to grasp, it says nothing about how he'll play on Sunday or in the future. It's about the past two weeks and his level of play compared to the first three weeks.
If you can't understand that then for the love of god just don't reply because I really don't know how to make it more simple.
