This is not directed at you (or anyone in particular), but annoys me so I am going to rant about it. I have heard several people, including announcers & commentators state "IU struggled against mobile QB's." Spoiler alert, EVERYONE struggles against mobile QB's to some degree. There are 0.00% of Defensive coordinators that will ever think or say "I love facing a really elusive QB!" or "I wish this statue we're playing this week was much quicker and able to get out of the pocket."
Of course if a QB can only run and is a terrible passer, that is another issue, but definitively a mobile quarterback is a problem for any and all defenses forever past & future.
Thanks, I feel better.
