Interesting comments in there and some interesting discussion on rivals about the subject, but this one stood out:
Ballenger is entering his third year in the program. Shouldn't he be running essentially the same playbook as Cody by now?At quarterback, Cody Hawkins’ 23 career starts dwarf the number made by Ballenger (none) and Tyler Hansen (two). Helfrich said whichever quarterback is the most efficient and gets the team in the end zone will be the one who wins the starting job.
Keep a couple of things in mind as this battle evolves: Helfrich said Hansen and Ballenger, both sophomores, will not be asked to run the same plays on offense as will Cody Hawkins, a fourth-year junior, due to Hawkins’ experience.
Secondly, Ballenger said he needs to improve on being more assertive, and Hansen said he needs to understand what defenses are trying to do. Asked what he needs to improve, Cody Hawkins said “manipulating” the opposing defenses, which includes changing plays at the line of scrimmage and other nuances that make veteran quarterbacks so valuable.
