re: What are the on-the-field reasons why Barnett or Cornwell aren't ready?

It sounded like each of the of the QBs, including Barnett, was given a real chance to show out and win the job in one of the fall scrimmages, but none of them did. Coker didn't do enough to win the job either but gets the nod due to having the most experience (which definitely counts for something at QB IMO). Can't blame the coaches if none of the other guys stepped up and showed they were ready.
