No it is not. And Reid is no longer the pass happy guy he was in Philadelphia. Hasn't been since he gotthe job in KC. They're running a diverse, sophisticated, well-balanced attack that stresses every level of an opposing defense.
And currently, the only thing I think Dallas' defense is doing particularly well is rushing the passer.
Reid still prefers the pass, always will as a West Coast proponent when the chips are down. A short pass is the same as a run.
What is different now is that the number of options that exist. This offense is not going to just go pass crazy because they depend on options to move the football, run and pass.
On any one given play they can have four options for the QB to filter through prior to the snap. These are choices, based on reading the defense. It is up to the QB on the field to communicate which option.
One option could be a sweep to Tyreek Hill, a run by Hunt, a designed run to Smith or even an exotic like a shovel to Kelce.
That is one of the reasons I laugh when people think this is the Alex Smith from the 49ers. He has a lot of decisions to make and usually he makes good ones.
