Miles and passing game

What is your take on Kraigthorpe? I appreciate that Miles kept him on, that is a quality I think people respect about Miles.
But
Does it in reality fit his narrative? I don't see enough emphasis on developing a QB from Miles. The biggest excitement is when our QB goes to california in the off season to train with a non LSU coach. It's like saying your on your own with becoming a passing QB. Can anyone including the most staunch Miles supporter give credence to our lack of development. How does a 68% run team have so much trouble getting a QB developed that it takes three years?
Other coaches have backups ready and playing well on the fly. That's with a much more balanced attack. I'm just trying to get a feel of where the lovers optimism is coming from?

If you are truly realistic about this, one has to agree the offense is coached by Miles with selective straw men in place for blame.
