New Sooner OC Seth Littrel has his hands full this year. Taking on a new role as an offensive coordinator is challenging; however, entering the SEC has amplified it tenfold. His offense will most likely feature an air raid attack and pass plays on approximately 65 percent of his snaps. Jackson Arnold will need to get hot quickly because he will see one of the nation's top defenders in week 4 when Pearce and his Volunteers come to Norman. Things won't get much easier after that, either.
