What do you expect Cam to say?
"I am a god awful passer. Josh has no choice but to call plays that maximize my strenghts. I can throw short/medium-range passes at 100mph, but I cannot do anything else. I have no touch, no pocket awarneness and I cannot throw it deep with any semblance of accuracy... and I can barely read a defense presnap... so I never adjust. I can run though, that I can do."
That being said, McDaniels should be able to get more creative in the red zone and design plays that use Cam's running ability as a decoy or something. Constantly coming back to the same ****ty option play won't cut it.
The QB and the personnel are a bigger problem than the OC... even if the OC is indeed part of the problem.
