based on this scrimmage.
Team has barely thrown on pads, isn't running the full offense, and is a slightly over a week into fall camp. Also how do I know the person reporting on the practice isn't a football imbecile with connections? Is this person savvy enough to know when the coaches might not be calling the same game for each QB instead choosing to focus on certain skills/elements for the individual player? Is there collusion between the OC and the DC to run certain defensive sets to see how an individual QB responds? Could it be that a more senior QB might be getting more complex looks from the defense while the less seasoned are getting more base packages? Believe it or not that's how coaches find out strengths/weaknesses in an effort to cure each QB's issues.
In other words this is all speculation from someone who isn't privy to the actual practice plan and is gauging their opinions based on the average fan's low-level football knowledge..
