How can you justify NOT starting AJ McCarron the rest of the season?

I do not think AJM should replace Andy this year. I wouldn't mind seeing a little shorter leash when he is struggling though. Folks say no QB could perform behind this line. They don't know this; they're just making it up. Andy, himself has had some fine games behind this line. he just hasn't been able to sustain it.
