Irvin said it best last week, we run a man-beat-man system not a scheme-beat-scheme system. Works well enough when you have top talent at each level of your offense, but it can't sustain injuries, and it's predictable.
Ben on the post game show earlier that some player he doesn't did not name on an opposing team in recent weeks said our offense is very predictable.
So basically our scheme doesn't help our players, it just gives them a framework to operate in, plus our coaches seem to be incredibly stubborn about it. My 2 cents
