As Big 12 history has shown, the impact of true freshmen can be significant.
Below is a look at some of the conference's true freshmen who could help their respective teams this season.
Texas Tech OG Jack Anderson: The Red Raiders are desperate for help along the offensive line. Inking one of the country's top high school guards could be an immediate salve.
Texas QB Sam Ehlinger: Though sophomore Shane Buechele remains the favorite to retain the starting job as the incumbent, Ehlinger will be an injury -- or rough Buechele stretch on the field -- away from being thrown into the fire himself.
