re: Who do you blame for RS not being "ready?"

Ok
Ever occur to you that Barkley is on the field cause they have nobody else AND he just happens to have handled it very well under fire while our coaches have not had to throw RS in that situation so we don't know how he would respond. It could have nothing to do with how the coaches have gotten either of them ready, just different circumstances.
To try and put it a bit more simply, if JJ and JL sustained injuries and Miles was forced to play RS as a starter, he may perform as well or even better than Barkley. It's not a fair comparison.
