I do think with Bernard, it is more about not feeling good about anybody they put out there than him playing great and winning the job. McD said he was disappointed with the overall play from the position both vocally and physically. He likes the way Klein communicated, but he doesn't seem to have the ability to play the position how he wants it played.
Reading between the lines, he really hasn't loved anything he had seen, but Bernard seems to have the most upside. I believe he will have Kirksey starting around week 4 if Bernard can't be serviceable.
