Alot goes into the running game from the QB position. Alot goes into the blocking scheme , from the QB position. JG would execute a running play into horrible situations. He also did not recognize obvious blitzes . He obviously did not have the ability to audible or change the play . The offense he was running had been simplified beyond reason. He either didn't have the ability to audible due to limitations placed on him by the coaches or his own inability to recognize defenses pre-snap/
If you wonder why guys like Manning or Brady always seems to have a good running game , no matter who is blocking or who is running , it all comes back to the pre-snap read. A simple example is the UGA game . UGA was overloading one side. An audible to change the run play to the other side , results in a big gain. The play would go right at the overload and die a quick death.
Get the QB play right , we will have a running game
