Define, "complexity." Fans like to bandy about these generalizations but rarely provide substance to bolster the argument.
A simpler scheme is generally regarded as allowing for less or quicker reads from the QB, right? When things get more complex, you generally get different route combinations or option routes based on reads made by the receiver and QB. These are dependent on pre and post snap reads, which are directly related to what the players are seeing on the field.
How many times have we seen receivers visibly frustrated at the end of a play? Everyone remembers Beasley (and he paid the price) but there were several times Witten was visibly frustrated as well.
All schemes have slow developing routes. They also have hot routes and checkdowns. But the QB has to recognize when to give up on a downfield route and get rid of the ball. If he saw the field well, why wouldn't he get rid of the ball?
That's simply ridiculous. Literally no one who knows football would say something that absurd. You don't reach the level of NFL coach if your scheme, "doesn't get WRs open." Linehan has always been pass happy and actually put together some prolific passing offenses during his career. Now we're to believe he can't scheme a guy open?
Can you see how the scheme doesn't force a QB to hold the ball, "too long," if he actually sees the field?
Here's what Cooper actually said-
"All the stop routes, I don't know if you noticed but we just couldn't really complete them, because they were literally giving us the go [route]. We called a stop route a third time, and I kind of looked at Dak like 'I don't want to run that', but he was like 'Just run it Coop'. I guess he had a second thought, and at the line of scrimmage, he gave me our go signal. Obviously, we're going to have to change it now that I've divulged that secret, but he gave me our go signal and I beat [the coverage]."
You like to appear to be above the nonsensical, hyperbolic ranting which plagues most fans. Yet it appears you took a simple explanation of how one play worked in one game and indicted the entire scheme.

There is Cooper's route charts from each game last year. Looks like he ran plenty of slants and crossing routes, too. You know... those routes you keep saying they don't run?
